Caption: Hard Target Interdiction course conducted in 1996 at Yakima Washington. The target behind the class was engaged by .50 caliber rifle fire from a little over 1400 meters. Note the group size. Winds were 6-14 knots depending on the angle of attack on the targets. Temperature was 110 degrees at a little over 3000 ASL. Rifles are a mix of Barret M82A1 and SR-25 Suppressed guns.
