Vital to the survival of the airborne division is the air-transportable parachute field artillery battery equipped with the M1A1 75mm pack howitzer. Each gun can be broken down into nine parachute loads. These are all tied together and dropped as a single aircraft load. If all goes well, they’ll still be all together on landing. The bundles can be quickly located by the crew and assembled so as to go into action in support of the parachute infantry regiments immediately.
