 They had the CAT team, a counter-assault team, which were the guys that hopped up on the stage with the long guns and the green jumpsuits and the helmets. Their job is to provide suppression fire in case there is an attack going on, and they're providing the heavy fire for that. And then there's the counter-sniper team. Counter-sniper team are Secret Service employees. They're not agents, but they are usually former military snipers.
