This is the military-style equipment used to respond to the attack in Orlando

It was not immediately clear whether Orlando police used any equipment provided by the Pentagon in responding to the shooting at Pulse nightclub, but photographs taken at the scene of the shooting show police wearing far more armor than is common on the average foot patrol by U.S. troops in a war zone, underscoring the threat they thought they could face.

One image distributed by the Associated Press depicts a SWAT team member with the Orange County Sheriff’s Department wearing armor over an olive-green suit that includes a throat protector to cover his neck, a groin protector that hangs below his armored vest and deltoid armor that covers the shoulders. He’s armed with a black submachine gun, which are favored by both SWAT units and U.S. Special Operations troops in raids because they are easier to aim in close quarters than a rifle. A black, tactical knife is strapped to his left shoulder.

Another AP image shows SWAT team members from the side outside of the night club. They’re wearing similar armor along with black tactical boots, similar armor and both submachine guns and handguns, which are strapped to holsters on their right sides.
