    1.  THE 88-MM. GUN

    Fie ld Marshal Erwin Rommel's use of the 88-mm.

    antia irc ra ft gun as an offensive an titank weapon in

    Libya has caused som uch discussion among Am erican

    soldiers everywhere th at this seems a good t ime to de

    scribe it . In plain Engl ish, there isnothings t range or

    unusual about the 88. To the question " I s it vu lnera

    ble?" t he answer i s "Yes!"

    Back in the 10-year period before H i t ler came into

    power, the German 88-mm. an ti air cr af t gun was de

    signed and built in secret. In those days the German

    Army was rig id ly limited as to men and mate rie l. I t

    is known that the designers of the gun were chiefly in

    terested in constructing a double-purpose ant iai rcraf t

    andant itank weapon. The news of the gun 's ant itank

    capabilities was not allowed to leak out, however, and

    not until the Nazis invaded P olan d did the w orld

    discover what the German designers had perfected.

    B asically, th e 88-mm . is a tra cto r-d ra w n gun for

    firing onmovingtarg ets (fig.1 ). I t hasara te offireof

    25roundsperminute, orsl ightlybetter, andis capable

    not only of a great volume of fire, but of extrem e

    accuracy against m oving targ ets of any type. This

    app lies to ta rg ets on the ground as well as those in

    the air. W h en the 88-mm. is to attack arm ored ve

    hicles, it is pro vided w ith a special arm o r-p iercin g

    projectile.

    Rommel generally sends the gun into posi tion under

    cover of m edium tanks. The tanks are then w ith

    draw n for offensive operations somewhere else,and the

    88-mm.begins its m ission of tryin g to pierce the armor

    of approaching hostile tanks .

    W h a t are the g un 's w eaknesses? F i rs t, it m akes a

    good targe t for dive bombers, even though one of its

    du ties is to oppose a ir cra ft. T he 88 has a h ard time

    placing i ts fire ondivebombers. They can come down

    at a furious speed, blast the 88, and get away success

    fully. B u t th e re ally imp o r ta n t w eakness of th is , or

    an y other gun, lies n ot in its ma nu fa ctu re bu t in its

    crew . T he gun is n ot a liv e; th e men a re . T hey know

    which will endthe bigg un 's usefulness to theA xis, but

    a detachm ent of p erh ap s 20 A m erican soldiers. To

    meet such a threa t , the crew wear their rifles s trapped

    to their backs in readiness for close combat.

    The na tu ra l question that a rises i s : "D o we have a

    comparable w eapon— if so, w h a t ? " F o rtu n ate ly , our

    respect, and we are building even bette r models. The

    clever tactics of the Germans, rather than the 88

     itself

    have been responsible for much of the g un s success.

    2 TANKS IN THE SPOTLIGHT

    Lately the Germans have been working their Mark

    I V tan k overtime, especially in Liby a. I t is a medium

    tank of 22 tons , ca rrying a crew of five (fig. 2 ) . Armed

    with one 75-mm. gun and two light m achine gu ns, it has

    been used chiefly as mobile, close-support artillery in

    desert w arfa re. The repo rted substitution of a more

    powerful 75-mm. gun may send the Mark IV back

    to its normal task of serving as the chief element in a

    bre ak thro ug h. I t s best possible speed is 31 miles per

    hou r. I n study ing the photograp h for identification

    purposes, note that the Mark IV has, on each side,

    eight small bogie wheels and four track-support

    rollers. Testing a captured G erman M ark I V tank,

    the British have discovered that it can be blinded by

    flame-thrower atta ck . A lthough the flames are not

    likely to enter the turret or the driving compartment,

    they will coat with thick soot all lookout points, in

    cluding the telescopic sigh ts on the gun. As a resu lt,

    the men in the tank cannot fire effectively until they

    have changed or cleaned their sights.

    The Germans also make wide use of the Mark III, a

    ligh t medium tan k of 18 to 20 tons (fig. 3 ) . Form er ly

    it was armed with one 37-mm. gun and two light

    machine guns, but in most cases the 37-mm. has

    been replaced by a 50-mm. I t s best possible speed is

    28 miles per hour, bu t it is much easier to maneu ver

    on the battlefield than the heavier Mark TV.

    The war in Africa has proved, however, that the

    Am erican M3, known to the B ritish as the G en era l

    G ra n t, has the best tan k arm or in the world. G en

    eral Grants' ' stay in the fight after as many as eight to

    ten hits by 50-mm. and smaller an tita nk weapons. I n

    at least one case, a G en er al G r a n t has continued to

    perform well after 27 hi ts. The new A m erican M4,

    known as the G en er al L e e , is even more reliable. I t

    has greater speed and more power, and is excellent for

    reconnaissance and pu rsu it. Am ong other improve

    ments, its 75-mm. gun has been placed in the turret

    instead of on the side. This change gives it an all-

    around field of fire.

    3 MECHANIZED WARFARE

    The tactics used by the Germans in mechanized

    warfare are of interest to every American in the field.

    German mechanized tactics are likely to follow certain

    set pa tte rn s. Nevertheless, it m ust be remem bered

    that German commanders are clever at changing

    standard tactics to fit the situation at hand.

    Under normal circumstances, the first German move

    is to order armored car patrols, supported by anti

    tank guns, to do a thorough job of reconnaissance.

    Motorcycle riflemen also lend support if the terrain is

  • 8/17/2019 (1942) Intelligence Bulletin, Vol. I, No. 1

    15/183

    8 INTELLIGENCE BULLE TIN

    suitable. These reconnaissance patrols are drawn

    from the reconnaissance battalions of the armored di

    vision. The size and makeup of each patrol naturally

    depends on the mission it has to perform. Sometimes

    the Germans even add a number of light tanks.

    These reconnaissance detachments not only report our

    movements and those of their own units, but are sup

    posed to be strong enough to put up a fight, if neces

    sary. While the patrols are trying to find out our

    strength, German air and ground observers are doing

    their best to detect our artillery and antitank-gun posi

    tions so that these may be dealt with when the main

    attack begins.

    Having decided where to strike, the enemy next

    brings forward his tanks, supported by motorized in

    fantry. He covers this move by a screen of antitank

    guns and tries to bring his forward elements, includ

    ing a company of Mark IV tanks, to within about

    2,000 yards of our own antitank guns and artillery.

    At this stage he generally tries to refuel his tanks

    under the protection of his forward detachments.

    The Mark IV tanks direct their 75-mm. gun fire on

    our antitank guns and artillery. Meanwhile, Mark

    III tanks assemble for battle, and often challenge our

    defended area at different points in strong, close

    formations.

    The enemy then decides where he wants to begin his

    main thrust. Having done his best to weaken the

    power of our defense by the fire of his Mark IV tanks

  • 8/17/2019 (1942) Intelligence Bulletin, Vol. I, No. 1

    16/183

      9ERMANY ARMORED FORCES

    and artillery, he opens a strong attack with his Mark

    III tanks, followed by motorized infantry and guns,

    and advances on his objective.

    In addition, he often directs at least one column

    (containing tanks, artillery, and motorized infantry)

    on some important locality in our area, such as a tank

    repair center. There may be more than one of these

    thrusts. As a rule, the Germans try to develop them

    into a pincer movement, with the advance columns

    pushing ahead to meet at the final objective.

    If one of the enemy's Mark III tank columns suc

    ceeds in penetrating any part of our defenses and es

    tablishing a fairly good position, motorized infantry

    is then moved forward to within a few hundred yards

    of the position. The infantry dismounts and goes into

    action, mopping up as rapidly as possible and organ

    izing the position. German machine guns and anti

    tank guns follow the infantry closely. Every effort

    is made to turn the captured position into an area, or

    a series of areas, capable of all-around defense against

    any form of attack. In this last operation, speed is

    emphasized.

    In Libya, the Germans often start these attacks late

    in the afternoon so as to have the advantage of fight

    ing with the sun behind their backs. In this theater

    of operations, the action is usually completed by

    nightfall. Either side is likely to counterattack soon

    after dark. Experience has shown that the Germans

    especially dislike this form of combat, and United

    Nations counterattacks begun at night have often suc

    ceeded in recovering', at small expense, ground lost

    during the day.

    It must be repeated that, although the Germans like

    to employ established and familiar tactics, they know

    how to change them when necessary. The best ex

    ample of this is the new German technique of bringing

    up artillery in close support of tanks, so that tanks are

    never required to face antitank guns by themselves.

    FOCKE-WULF—FW190

    A new addition to the Germ an A ir Force is the

    F ocke-W u lf— F W 1 90. The G erm ans claim th at it is

    the fastest and most easily maneuvered fighter in the

    world. However, in spite of its speed and maneuver

    abili ty, the B rit ish have been ableto destroy a number

    of these p lanes and recently cap tu red one almost in

    tact.

    As shown in the accom panying photograph, the

    F W 1 90 bears some resem blance to our P 36 p ursu it

    plane,which hasbeenin service for severalyea rs. The

    wing form seems s imilar to tha t of the Bri t i sh "Spit

    I t is well protected by armor, is heavily armed, and

    carries m ore cannons th an is usual w ith planes of

    similar type.

    A lthough the FW 190 has not yet been known to

    c ar ry bombs, it is possible t ha t bomb ra ck s may be

    2. PARACHUTISTS

    a. Introduction

    A good many Am erican fighting men have said that

    theywould like to get a clearer mental picture of Ger

    manparachutists— what they looklike,howthey train ,

    what their standard tactics a re , and in general how

    theydotheirjob.

    A common mistake is to imag ine tha t the German

    parachutis t is an ordinary infant rym an who, on land

    ing,goesintocombat asague rrilla fighter op era ting by

    himself, w ith help from any fellow -parachutists he

    mayhave the luck to meet. Actually , a German para

    chutist is a thoroughly traine d specialist who fights as

    part of a well-organized unit. The G erm an A rm y

    teaches him to believe that h is is the most impor tant

    ofalljobs—thatheisevenmorevaluablethantheaces

    of the G erm an A i r F orc e. A fter he has h ad a long,

    tough tra in in g in a p a ra c hu tis ts ' school, he is p re

    pared not merely to jum p well, but also to fight well.

    Infact, teamwork is the Germanp ara ch utist 's guiding

    principle.

    b. Training

    In choosing men who are to be sent to a parachut

    ists'

    school, the German Arm y selects candidates who

    are young, athletic, quick-w itted, and aggressive.

    Many of them are chosen with regard to certa in spe

    cial abilities (medical, engineering, and so on) which

    are ju st as m uch needed in parachute operations as

    in any other k ind . D u rin g the tra in in g, em phasis is

    placed on exact procedures; for instance, a man packs

    a p arach ute w ith special care if he knows th at he

    himself is going to use it. A fter p roper physical

    conditioning, the candidate w orks from a jum ping

    tower, practicing landing methods und er different con

    d itions , ^h e school also requ ires , and develops, fear

    of h esitatio n a t th e command " J u m p ! " ma y cost the

    candidate h is membersh ip in a parachute company.

    However, parachute jum ping is only a small pa rt of

    the candidate 's tra in in g, inasm uch as the Germ an

    Army hopes to make h im a useful member of a crack

    combat o rgan ization . He must know how to take par t

    in w hat is called a " v er ti ca l e nv elo pme nt"— th at is,

    the capture of an area by air-borne troops.

    c. Tactics

    A irfields and railw ay and highw ay junctions are

    likely to be among the foremost objectives of vert ical

    envelopmen ts. Usua lly theybegin a t dawn. Tomake

    the parach ut is t 's task less difficult, the Germans send

    out bombers, dive bombers, and fighters ahead of time

    to place fire on th e d efe nd ers ' gun p osition s an d to

    drive gun crew s to cover. Special atte ntio n is paid

    to ant ia ircraft ba tter ies .

    A fter an hour or m ore of continuous a ir attack,

    one of several possible events may take place, since

    German tactics a t th is stage are not s tandard ized . I f

    reconnaissance has shownth at the terr ain is favorable,

    gliders may descend and t ry to land their troops

    (usually ten to a glid er) in a su rprise move u nd er

    coverofthe ai r attack.

    If the landings are successful, the glider-borne

    troops w ill m ake every effort to k ill or c ap tu re the

    defending gun crew s, thereby p av in g the w ay still

    further for th e a rr iv a l of th e p ara ch ute tro ops. O r,

    i t may be that gliders will not beused at all, and that

    parachutists will berequired top erform this operation

    by themselves. Much will depend on how s trong the

    Germansthinkthegrounddefensesare.

    Even though the parachut is ts will use tommy guns,

    rifles,

    or grenades while they are descending, ex

    perience has shown th at this is the tim e when the

    defending ground forces will get the best possible re

    sults with the ir fire power. The Germans cannot aim

    effectively w hile they a re descending. A s they a re

    nearing the ground, andfor the first few m inutes after

    they land, they make idea l ta rge ts . I n Crete, for ex

    ample, the Germans suffered enormous losses a t th is

    stage. Nevertheless, it m ust be rem em bered tha t if

    there is an airfield to be gained , the Germans appar

    ently will sacrifice their parachuti st s freely in a con

    centrated effort top ut the defende rs ' gun crews out of

    action. The German command will be chiefly in te r

    estedin gaining enough control of an airfield to perm it

    the landing of b ig t ranspor t a ircraf t like the Junke rs

    which carry twelve men (plus the pilot, observer,

    and reserve pi lot) or heavy equipment and fewer men.

    If the parac hutists cannot overcome the defenders ' gun

    crews, the opera tion is likely to be a fai lure from the

    G erm an po int of view. To p ut it briefly, the para

    chu tis ts (perhaps supported by g lider-borne troops)

    are shock tro ops, and it is upon th eir fighting that

    future control of the airfield hinges.

    Different Germ an tactics may be expected, however,

    when a parachute uni t is dropped on an area which in

    itself maynot interest the Germans, but which maybe

    reasonably near an airfield, a junction, or a communi

    cations center. I n this case, w hatever units are

    dropped will quickly t ry to assemble as a coordinated

    fighting force and then advance to c arry out their

    mission.

    The German method of re leasing parachuti st s from

    t ra n s po r t p lan es over an y given a rea is so carefully

    worked out tha t very l it tl e is l eft to luck . The p lanes

    a re likely to a r rive in flights of th ree . Arr iv ing over

    get read y. H a lf a m in ute before th e ju mp , he shows

    signal to jum p. I f he waves both flags, crossing them

    back and forth, he is signalling " D o n 't j u m p ! " A t

    night, signals are givenby colored flashlights, in which

    case red m ay m ean " G et re ad y," green m ay m ean

    "Half aminute togo ," and white maymean " J u m p ! "

    A leader in each plane gives the s ignal to jump by

    soundingan ins trument like an automobile horn. Be

    fore jumping, the parachut ists at tach the r ing of their

    parachutes to awire running along the inter ior length

    of the a irc ra ft on th e rig ht-h an d side. T he ju m p is

    made th rough the righ t-hand door, the ring yank ing

    the cord of the parachute, which opens automatically

    after a 5-second delay (equal to a d rop of about 80

    feet).

    Equipm ent containers are dropped through

    the door on the left-hand side of the plane. Each

    container includes the equipm ent of th ree or four

    men, and is th rown out when, or jus t a fte r, the men

    jump.

    The twelve m en and four containers carried

    by each p lane a re supposed to be d ropped w ith in 9

    to 10 seconds. W h en th ere is a delay, or when all

    the parachut is ts cannot jum p while the plane is over

    the desired area, th e p lane w ill sw ing a ro un d in a

    circle and make a second run across the area.

    Jumping at an a lt itude of 300 to 500 feet, the para

    chutists will reach the ground within 20to 30seconds.

    The Germans have found it useful to a ttach pa ra

    chutes of different colors to different kinds of loads .

    For example, a soldier's parachute may be a mixture

    of green and brown, to make him less conspicuous on

    the ground and to serve la ter as camouflage for cap

    tured motor vehicles. On theother hand,white para

    chutes may be used for equipment containers

    3

    and

    pink for medical supplies. The Germans are likely

    to change the meaning of these colors from time to

    time.

    Since parachutists can request extra supplies

    by laying strips of white cloth on the ground in cer

    tain formations, there is always a possibility that the

    opposition willfindout the code, and deceive German

    aircraft into dropping such supplies as ammunition,

    food,andmedicine.

    SectionIII. BOOBY TRAPS

    1. GENERAL

    A booby t rap is any form of concealed explosive

    which causes destruct ion of men, equipment, or com

    munications. I t is so placed tha t it will be acci

    dentally set off by the enemy or will function auto

    matically by means of a time mechanism. Although

    explosivesa re theno rmal method of destruction, booby

    t raps may also be designed to utilize flares or incen

    diarybombs.

    1

    The reason for em ploying such tr aps is to create

    an a tmosphere of uncertainty and to make the enemy

    very cautious and uneasy, thereby lowering his morale

    and slowingu p his actions.

    Since booby t raps get the ir success from surprise,

    both the charge and the operating m echanism are

    either concealed or made to resemble some common,

    harmless object.

    2. OPERATION

    In almost every case booby t raps may be opera ted

    byone of the following m ethods:

    O F USE

    The following genera l methods a re o rd inarily used

    by the enemy in sett ing boobyt ra p s ; by s tudying how

    the t raps a re set, we can more easily find and safely

    destroy them.

    a. Keeping Normal Appearance

    Every a ttempt is made to d is tu rb the surroundings

    as little as possible and to remove or h ide carefully

    all signs of p reparat ion a fter lay ing the t rap .

    b. Small Spaces

    The smaller the space in which the t ra p is la id—for

    example, passages, stairw ays, dugout inclines, and de

    files— themore chance there will beof the tr a p 's being

    sprung.

    Miscellaneous Booby Traps

    I t is repo rted that the Germans in L ibya have laid

    antilifting devices, using a pull -igni ter, under mines.

    Tar barrels have been left on roadsides, with three

    large shells of about 6-inch caliber in them, the whole

    device to be fired electrically.

    At points where the road is cut into a hillside,

    stick grenades have been hung by w ire down the

    1. IN LIBYA

    In Libya the Germans have been laying rows of

    anti-personnel mines in front of their plate-shaped

    antitank mines inan effort tomake the cleaningupof

    minefieldsmoredangerous.

    The anti-personnel mines have push-igniters, and

    are usually laid with only an inch of the antennae

    visible. Although the disturbed earth is carefully

    smoothed back into place, the appearance of the

    danger spot is likely to be different from that of the

    surrounding ground. A sharp eye can detect the

    difference, especially sincethe Germans,after smooth

    ing back the earth, don't seem to worry much about

    disguising their minefields elaborately.

    German antitank mines in Libya are usually laid

    sothatthetopsofthepush-ignitersareflushwiththe

    ground. As in the case of the anti-personnel mines,

    not much concealment is attempted and the disturbed

    earth usually gives away the location.

    For safety's sake,be on the lookout for trip wires.

    No mines with pull-igniters have been captured, but

    it is known that the Germans are using them.

    are occasionally laid in rows or in a checkerboard

    the first mine, they

    SectionV . TRAINING METHODS

    1. GENERAL

    Present German military thought centers around

    the task force idea. The task force usually consists

    of all arms and services working under one com

    mander to perform a single specific mission. The

    Germans spend a great deal of time developing their

    task forces,which may vary in size from a squad toa

    group of armies. The elements of the task force are

    sodrilled that theywill lose their identity as separate

    unitsandmergeintoasmooth-workingtask-forcecom

    bat team. As a result of this joining together of

    units,

    the Germans stress cooperation, with everyman

    andunitdoingadefinitejob.

    According to the best German military thought,

    there has been a change in the nature offighting and

    also in the basic objective of battlefield combat

    itself.

    Formerly, the supporting arms made it easier for the

    infantry to surround and destroy the opposition.

    Now, even the destruction is done by the supporting

    arms—mainly artillery and combat aviation—with the

    in fan try operating only in a supporting role. The

    mission of the supporting arms, according to the

    In

    this change-over

    everyeffort

    is

    made

    to

    discourage rivalry betweenthe

    components

    ofthe

    team.

    For

    example, there

    are no

    songsabout the infantry beingbetter than the cavalry

    and

    the

    engineers being best

    of all.

    There

    are no

    inter-company

    or

    inter-battery athletics. Onthecon

    trary, every opportunity

    is

    taken

    to

    develop team

    work among

    the

    par t s

    of the

    force. Cooperation

    between

    the

    units

    is

    encouraged. This

    is

    impressed

    all

    subordinate commanders—so much

    One important phase

    of the

    training

    of

    combined

    arms

    is

    theuse

    of

    practice ammunition. This

    is

    reg

    ular ammunition with reduced bursting charges.

    The

    men tak ing part must

    be

    careful

    in

    handling these

    munitions, soastoescapeinjury. Use

    of

    realammu

    nition

    in

    is

    very valuable. Many

    men

    are

    accidentally killed

    by

    fire

    of

    friendly troops lacking th is valuable experience.

    During

    the

    training phase,

    the

    importance

    of sur

    prise

    in

    combat

    is

    continually emphasized. Accord

    ing

    to

    German teachers, surprise

    by

    three general methods: first,

    With regard to infantry tra in ing, there is much

    more emphasis on

    volume

    of

    fire than

    on

    accuracy.

    Riflemarksmanship isnotstressed,andthere isgood

    The headlight is mounted on the le ft-hand side of

    th e vehicle, about 3 to 4 feet from the gro un d. The

    headligh t-opening for passage of light is flat-shaped.

    A 35-w att bulb gives off lig ht to the r ea r, ag ain st a

    m i rro r which is half oval in shape. The m irro r, in

    tu rn , reflects the light forward through a glass panel

    under the overhanging hood.\ The g lass panel spreads

    the light, which extends to the f ront a d is tance of 100

    to 130feet. The longest width of the l ight is about80

    b. Interval-Judging Rear Light and Stop Lights

    The panel containing the lights is d ivided into two

    parts, the upper half and the lower half. The upper

    half includes the interval- judging device itself, while

    the lower half conta ins the usua l r ed ta il-ligh t and a

    yellow " s t o p " light, which goes on when the b rakes

    are put on. The interval-judging device has four

    small windows, r ec tangular in shape and grouped in

    pairs.

    W hen the device is working, a yellowish green

    The use of the in te rva l- judging device is based on

    the way the hum an eye sees lights a t different dis

    tances. W hen viewed from a certa in d istance, lights

    close to each o ther appea r to be ju st one light. Fo r

    instance, a t 325 yards the ligh ts sh in ing through the

      This includes, among other

    things,  the  putting together  of   other

    information they have deals wi th field pos t numbers , organiza

    information

    forthe

    questioning

    At questioning, such material  is  used  to   convince  the   prisoner

    that  any   refusal  to   give information  is   useless,  as the  enemy

    already  has  exact knowledge  of   Germ an military matters.  If

    the prisoner refuses,  his   attitude  is   respected— even   if a few

    threats are made  in   the first place.

    A

      few   days later  the  prisoners are moved from  the  first place

    to

     a

      a

     political questioning takes p lace.

    questions here deal with  the   relations between   the   Army and

    the Parti/, with the prisoner's own feeling towards National

    Socialism, and with the military and economic situation. As

    the Englishman in this case wants to get an idea of the political

    attitude of the armed forces, purely military secrets are not

    mentioned. This questioning is carried out by an officer in

    civilian dress, who frequently speaks German less well than

    the  offi er  who ashed the first questions.

    Some hours later the prisoners are taken in special transport

    to the real "questioning camp." There a medical inspection

    takes place to establish the general state of the prisoners^ health

    as regards feeding, etc., then two to three weeks confinement,

    either alone or with one other prisoner.

    During this time the prisoner is questioned several times a

    day by Intelligence Corps officers on purely military matters; the

    statements of the various prisoners are played off against each

    other. Questions are asked about peacetime garrisons, military

    developments, the use of units in previous campaigns, and so

    on.  Listening apparatus is installed in rooms in which two

    prisoners are put together. Germ ans in uniform, who have mi

    grated to England, are also used as spies.

    On one occasion a former Austrian in the uniform of an Air-

    Force

     offi er

      introduced himself to a newly-arrived prisoner. He

    spoke German with a Viennese accent and claimed to be a

    reserve offi er  in a certain unit. He lived in a two-man cell w ith

    the prisoner and in the course of conversations tried to gain

    information on military and technical points of the prisoner's

    arm of the service.

    The strict isolation in the "questioning" is supposed to induce

    a feeling of loneliness and helplessness in the prisoner, in order

    to break down his resistance. When the Intelligence Corps

    officer considers any further questioning useless, the prisoners

    are sent to officers' or other ranks'

    1

      prison camps, as the case

    may be.

    Recent reports show tha t similar procedures are carried out in

    othertheaters of war besidesG reat B ritain .

    INTRODUCTION

    The Japa nes e m ust be recognized as vicious enemies

    who are h ighly t ra ined and exceptionally well organ

    ized. They have p roved themselves formidab le foes

    in bat tle . Their calculated advances, successfully car

    r ied out, have shown them to be mas te rs of detailed

    pla nn ing and execution of policies.

    Nevertheless, the early successes of the Japanese

    were not the resul t of brand-new tactics or new super

    w eapons. Basically, their tactics are no different

    from those em ployed by other m odern arm ies and

    thei r equipment i s, as a whole, infer ior to tha t of the

    closer to the areas of battle than the bulk of our

    w ith surprise and getting the " j u m p " on all the

    modified th e ir basic tactics to a da pt th em to jungle

    usually wasmade ahead of each operation, and com

      General.

    — The Jap ane se used infiltration tactics

    to g rea t adv an tage in conquering the jungle areas

    now in thei r possession. Th is k ind of a ttack iswell

    suited for jungle w arfare, especially when the attack

    ing forces havemore troops than the opposi tion. And

    in n ea rly every place w h ere th ey fought d urin g the

    first few mon ths of the war, they were ab le to mass

    a much larger fo rce than the Uni ted Nations.

    Therewasnothingpart icular ly newabout theJapa

    practically the sam e as those set out in our Basic

    F ield M anual on " J u ng le W a r f a r e " (F M 31-20).

    ered the bestbasis for combatting the Japa nese .

    (2)  Methods Used.—Usually the Japanese avoided

    a ttacks to the f ron t of Uni ted Nations fo rces, except

    in cases where the enemy sought to deceive our troops.

    The f ron ta l a ttacks genera lly were made wi th a com

    p ara tiv ely small n umb e r of men. T hese w ere armed

    wi th ligh t machine guns, which were fired a t a rapid

    ra te in order to m ake our troops believe a much

    larger force was a ttack ing . Also, on numerous occa

    sions, the Japa nese set off firecrackers to add to their

    efforts to confuse.

    around the flanks of our forces, and, in m any in

    stances, patro ls crept through gaps in our lines to

    ireach the rea r. The pa tro ls usually were small, num

    ibering from two to a few dozen men. They were

    ilightly dressed, and genera lly were armed with light

    1machine guns an d grenades. E ach of th e m en car

    iried enough com pact food to last for several days.

    By collecting food from the countryside, they often

    had enough to las t much longer. These men had been

    itra ined and hardened to wi thstand many discomforts.

    All, or nearly all, were expert swimm ers and handlers

    of small boats. They had been instructed to look

    upon woods and wa te r as th ings to assist them—not

    as obstacles.

    The in filtra ting Japanese pa tro ls had various mis

    sions. In all cases camouflage was widely used , and

    all movements w ere m ade as silently as possible.

    Some of th e J ap a ne se w ho acted as sn ip ers p ain te d

    their faces and hands g reen to conform to the leaves

    of the trees and covered th eir clothes w ith leafy

    tied themselves wi th ropes so they would not fa ll out

    the positions wi th m or tar s, or infiltra te between our

    positions.

    In their infi lt ration tactics, the Jap an ese moved fast

    at certain t imes and veryslowlyat others. They stood

    in rice-field d itches for hou rs, up to their necks in

    water,w aiting for targets to appear . They lay hidden

    in underbrush for long periods wai ting for chances to

    advancew ithout being seen.

    Often when the opposition counterattacked, the J a p

    anese hid unt i l opposing troops had passed, and then

    firedonthe irflanks and rear .

    On some battle fronts the J apanese fortified their

    positions after infiltrating th ro ug h and a ro un d the

    opposition flanks. These positions were prepared for

    all-around defense, and they included an unusually

    large number of foxholes with connecting trenches.
