The tactical team takes the door.
A smoke machine fills the halls while strobe lights flash and speakers blare a distorted, looped recording of people screaming.
The entry teams hunt and neutralize threats from Hallway A and Hallway B.
The RTF ties down tourniquets.
The shooters return fire on the gunman, while others drag casualties to safety. The rounds are blank, but the boom of the shotguns is very real.

When an active shooter starts, the first officers on the scene may be people who wrote speeding tickets 10 minutes prior. Basically, it's more likely that a local police officer will be closer to the scene than a tactical team, which may have to travel across the state.
That's why Patrolman First Class Nick Betcher of the Sykesville Police Department treats this drill as a real-world scenario with real-world consequences.
