Every gun section in the 898th was equipped with
one quadruple mount .50-caliber MG. These truck-drawn, trailer-mounted guns
were capable of pouring a deadly hail of lead at low-flying aircraft. They were
also devastating against ground targets, although as an automatic weapon over
11mm in caliber, by the international conventions then in force, this weapon
was only to be so employed in self defense.
