EXERCISE BLACK ORYX: A U.S. Army High Mobility Rocket Artillery System (HIMARS) fires a rocket during Exercise Black Oryx in Jordan. Here’s a 2011 post with background on HIMARS’ development and initial procurement. This second post (from November 24) discusses new ways the Army and Marines are employing HIMARS. USMC F-35Bs can “spot” targets for GPS-guided GMLRS rockets fired by HIMARS. The Army and Air Force are developing innovative tactics for quickly deploying HIMARS in a forcible entry mission. The acronym is HIRAIN (HIMARS Rapid Infiltration). As the post points out, “until HIMARS and GMLRS came along there was no easy to provide instant precision artillery support.”
