The M-102 105mm howitzer is used in helicopter air mobile and light infantry operations. The M102 began replacing the M101A1 105mm Howitzer starting in 1964 during the Vietnam War. Since 1964, the Army has acquired 1,150 M-102 towed howitzers. The M102 was replaced in the active Army by the M119A1 105mm towed howitzer starting in the late 1980s, although the M102 is still found Army National Guard units (2005).

Howitzer, Light, Towed: 105 mm, M-102

When emplaced, the very low silhouette Howitzer, Light, Towed: 105 mm, M-102 has a high volume of fire that compensates in large measure for the lower explosive weight of the projectile compared to the Army's 155mm and 8-inch howitzers. It has a roller tire attached to the trail assembly of the M102 permits the weapon to be rotated 360 degrees around a firing platform, which provides the pivot for the weapon. The weapon can be elevated from -5 degrees to a maximum of 75 degrees.

The M102 carriage is lightweight welded aluminum, mounted on a variable recoil mechanism, nearly 3/4 ton lighter than the M101A1 Howitzer. The weapon is manually loaded and positioned, and can be towed by a 2 1/2 ton truck or High Mobility Multipurpose Wheeled Vehicle (HMMWV), can be transported by UH-60 Black Hawk helicopters, or can be dropped by parachute with airborne units.
