The M198 Medium Towed Howitzer is a 155mm field artillery howitzer that provides general support field artillery firing by providing both nuclear and nonnuclear firing. It is constructed of aluminum and steel, and is air transportable by CH-47/CH47D helicopter, and C-130 or larger fixed-wing aircraft.

The M198 155mm Medium Towed Howitzer is deployed in separate corps- and Army-level field artillery units, as well as in artillery battalions of light and airborne divisions. In the USMC, the M198 provides field artillery fire support for all Marine Corps Air Ground Task Force organizations. The M198 provides increased range, and improved reliability and maintainability over the former standard towed 155mm howitzer, the M114A2 Howitzer. 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.
