Wildcat’s 0.50 caliber M3M Heavy Machine Gun....Designed to counter threats such as Fast Attack Craft, it can also be used in the air-to-ground and air-to-air roles.

Note. Has anyone heard of utility aircraft using their door guns in an air to air role? Does the Wing train Marine Door Gunners in air to air? I know Helo Pilots traing to maneuver against aerial threats but never heard of this before...

The Wildcat’s 0.50 caliber M3M Heavy Machine Gun can fire over 1000 rounds of incendiary armour piercing shot per minute.
