The MGM-140 Army Tactical Missile System is a tactical ballistic missile designed and manufactured by the US defense company Ling-Temco-Vought (LTV), and later Lockheed Martin through acquisitions. It uses solid propellant, is 13 feet (4.0 m) long and 24 inches (610 mm) in diameter, and the longest-range variants can fly up to 190 miles (300 km). The missiles can be fired from the tracked M270 Multiple Launch Rocket System (MLRS) and the wheeled M142 High Mobility Artillery Rocket System (HIMARS).

A tactical ballistic missile (TBM), or battlefield range ballistic missile (BRBM), is a ballistic missile designed for short-range battlefield use. Typically, range is less than 300 kilometres (190 mi). Tactical ballistic missiles are usually mobile to ensure survivability and quick deployment, as well as carrying a variety of warheads to target enemy facilities, assembly areas, artillery, and other targets behind the front lines. Warheads can include conventional high explosive, chemical, biological, or nuclear warheads. Typically tactical nuclear weapons are limited in their total yield compared to strategic nuclear weapons.
