Sappers treck California hills at night
A U.S. Army Reserve combat engineer Soldier from the 374th Engineer Company (Sapper), headquartered in Concord, Calif., checks his watch before a night land navigation course through the hills of Camp San Luis Obispo Military Installation, Calif., July 15, during a two-week field exercise known as a Sapper Leader Course Prerequisite Training. The land navigation course began after dark and most Soldiers didn't finish until after midnight after trekking for miles through the steep hills. The unit is grading its Soldiers on each event to determine which top ones will earn a spot on a "merit list" to attend the Sapper Leader Course at Fort Leonard Wood, Mo.
