Sappers treck California hills at night
U.S. Army Reserve Combat Engineer Soldiers from the 374th Engineer Company (Sapper), headquartered in Concord, Calif., hover around 1st. Sgt. Raquel Steckman after submitting their score sheets for a night land navigation course at Camp San Luis Obispo Military Installation, Calif., July 15, during a two-week field exercise known as a Sapper Leader Course Prerequisite Training. The unit is grading its Soldiers on each event to determine which ones will earn a spot on a "merit list" to attend the Sapper Leader Course at Fort Leonard Wood, Mo. (U.S. Army photo by Master Sgt.
