Основной режим огня - полуавтоматический.
>EFFECTIVENESS AND CONTROL OF AUTOMATIC OR BURST FIRE
>7-32. Automatic or burst fire is inherently less accurate than semiautomatic fire. The first fully automatic shot fired may be on target, but recoil and a high cyclic rate of fire often combine to place subsequent rounds far from the desired point of impact. Even controlled (three-round burst) automatic or burst fire may place only one round on the target. Because of these inaccuracies, it is difficult to evaluate the effectiveness of automatic or burst fire, and even more difficult to establish absolute guidelines for its use.
Для чего нужен автоматический огонь они сами не знают и словами сформулировать не могут.
