“Moving into a T-intersection really required a fire team to negotiate things safely. Ya feel me? The guy controlling the team’s movement got them to the split in the hall, assessed the danger of moving into the space, and then coordinated the forward movement. But don’t forget about that rear-facing dude so you don’t get smoked in the pooper. The basics of it are pretty simple. Two guys on opposite ends of the hall approach, then pie the corner to take control of the immediate risk of stepping out. If there’s someone there, you assess, address, and advance. Spread the lead until you own the space. Ya know? Once you’re clear, the third and fourth man move to the opposing wall and each take a direction. The first and second then swing in the hall. Got it all wrapped up? Good. The crew then moves back into a rolling “T” which is three front and one facing rear—and the whole hallway advance starts all over again.”
