Guided Projectiles And The Close FightMG Carl Ernst, FA Journal, Sep-Oct 1999
artillery and mortar fires must beable to support maneuver at muchcloser ranges than currentlyimagined.
(because of minimum safedistances) the maneuver commandermust stop the firing of indirectsystems long before it would betactically prudent on the battlefield.
the issue (is) logistics. It willcome down to a matter of trucks andprojectiles.
