The High Mobility Artillery Rocket System is a mobile launch platform that carries six 13-foot long, 9-inch wide rockets with 200-pound warheads.
The U.S. Army and Marine Corps mount the systems on the back trucks they can drive into position to obliterate an enemy force.
Marines with 2nd Battalion, 14th Marine Regiment fired their HIMARS a few weeks ago using the new Guided MLRS Unitary Rocket that features a precision strike capability.
While conducting a simulated raid they fired their rockets at a number of targets at White Sands Missile Range, New Mexico. (And they were even kind enough to place cameras downrange to catch the destruction of the targets.)
