Two M142 High Mobility Artillery Rocket Systems fire at targets after offloading from a C-17 Globemaster III aircraft, Jan. 31. The systems were prepared for the HIMARS Rapid Infiltration (HI-RAIN) exercise involving airmen from the 728th Airlift Squadron and soldiers from 17th Fires Brigade, 7th Infantry Division. The HI-RAIN exercise consisted of using a C-17 to transport the HIMARS units and their crews from McChord Field to Hunter Liggett, Calif., which acted as a theater environment. Once there, crews fired on a stationary target using the HIMARS and then were immediately extracted by C-17 from the launch site.
