One shooter. You are hearing sonic cracks after the boom as the bullet goes supersonic after leaving barrel. When bullets hit flesh they go “Thwack”. When bullets go by you the “whiz/buzz”...that’s the airflow behind the bullet...and hard to hear unless its pretty close to your head. Impact on grass, steel, concrete sound different too....plus the echos of the buildings, and the echo of the blast in the room due to the compensator/flash suppressor add to the confusion. One shooter, using multiple, pre-loaded, pre positioned guns with good firing arcs and he just maneuvered around as long as he could until he took the cowards way out. Evil, cowardly bastard.
agreed, thats pretty much what I heard.
Good post DCB.
