Navy Target 103

One of five practice targets used by the Navy and Air Force in the Imperial Valley. Each target is approximately 300-feet across, and consists of concentric circles, made of dirt and old tires, that surround a central "bulls-eye" mound. Some of the center mounds are topped with target objects, such as the hulks of tanks and other military vehicles. The targets are struck with inert practice bombs and straffed with 20 mm and 50 caliber machine gun fire.
