Shock and Awe, stateside.

Mr. Holmes had apparently planned the attack for some time: He wore a
gas mask, body armor, a tactical helmet and was dressed completely in
black. He entered the theater with an AR-15 assault rifle, a Remington
12-guage shotgun and a 40-caliber Glock handgun. A fourth gun, another
Glock pistol, was found in his car.
