Features: The M198 Medium Towed Howitzer is a 155mm field artillery howitzer. It is constructed of aluminum and
steel, and is air transportable by CH-53E helicopter, and C-130 or larger fixed-wing aircraft. The M198 provides
increased range, and improved reliability and maintainability over the former standard towed 155mm howitzer, the
M114A2. The use of rocket-assisted projectiles significantly extends the range, lethality, and counterbattery fires
of the direct support artillery battalions. The M198 fires all current and developmental 155mm ammunition.
Inventory: 541
Background: The first 10 M198 Howitzers were delivered to the 10th Marine Regiment in January 1982.
