Indeed, all the &quot;tribarrels&quot; (equivalent to the M2 Browning used in Vietnam (or, rather, back from 1933 to today, it&#x27;s a keeper)) could be&#x2F;were slaved to the anti-artillery and air network, and could be automatically taken away from their operators to stop an incoming barrage.<p>They had proximity fuzed Claymore style anti-&quot;buzz bomb&quot; defenses, but arming those was problematical for a zillion reasons, the best defenses were as they are today, sharp eyes and trigger fingers.  Later killing a buzz bomb team that killed a super expensive tank and its crew was not considered an acceptable exchange.
