The M109 is an American 155 mm turreted self-propelled howitzer, first introduced in the early 1960s to replace the M44. It has been upgraded a number of times, most recently to the M109A7 formerly known as the M109A6 Paladin Integrated Management (PIM). The M109 family is the most common Western indirect-fire support weapon of maneuver brigades of armored and mechanized infantry divisions. The M109A7 shares common chassis components with the Bradley Fighting Vehicle (BFV) such as the engine, transmission, and tracks.

The M109A7 can sustain a one-round per-minute rate of fire and a maximum rate of fire of four rounds per-minute. The M109A7 is 10,000 lb (4,500 kg) heavier than its predecessor, and it has the capacity to grow to 110,000 lb (50,000 kg). The M109A7 can travel faster than previous versions at 38 mph (61 km/h) and is more maneuverable than a BFV. The testing included RAM, mission and ballistic hull and turret testing. The M109A7 was slated to begin LRIP by 2013. The U.S. Army planned on procuring a fleet of 580 sets of M109A7 howitzers.
The M992A3 Field Artillery Ammunition Supply Vehicle (FAASV) is built on the chassis of the M109-series howitzer. It is also colloquially referred to as a “cat” (referring to its nomenclature, CAT: Carrier, Ammunition, Tracked). It replaced the M548 supply vehicle. Unlike the M548, it is armored. This ammunition vehicle has no turret, but has a taller superstructure to store 95 rounds with a corresponding number of powders and primers. There is a maximum of 92 conventional rounds, 45 each in two racks, and 3 M712 Copperhead rounds.
