Inscription. The 155mm Howitzer, M109, is an armored tracklaying vehicle and a highly mobile combat support weapon. It is air transportable in support of airborne operations and has an amphibious capability when equipped with a flotation kit.

The M109 was adopted in 1964 and was extensively employed on the battlefields of Vietnam.

A hydraulic system provides power for traversing and elevating the cannon and for ramming the projectile. Manual operation is possible in the event of power failure. Two recoil spades located on the rear of the vehicle (one behind each track) are provided to improve stability of the cannon in the firing position.
