A trio of U.S. Navy SEALs cover their arcs of fire while moving through water.
The SEALs are wearing woodland Battle Dress Uniforms (BDU), woodland boonie hats and the SEAL in the foreground is wearing matching face camo paint.
The use of woodland camo and CAR-15 carbines indicates that this photo comes from the late 1980s/ early 1990s.
SEALs recently moved away from wearing woodland BDUs when deployed, although they are still worn by BUD/s trainees.
