What does the number 2-man do when entering a center fed room?

The number 2-man in a tactical operation entering a center-fed room is primarily responsible for performing buttonhooks. This maneuver involves making a quick, sweeping action in the room to ensure that the area is clear of any threats. By using this technique, the number 2-man effectively observes the room from a position that allows for optimal visibility and safety, ensuring thorough coverage of potential hiding spots or dangers.

In a center-fed room, which typically has access points on both ends of the space, the buttonhook approach allows the officer to move rapidly into the area while maintaining awareness of their surroundings. This tactical movement assists in efficiently clearing the room and is integral to maintaining control of the situation.

The other choices, while important in different tactical scenarios, do not specifically apply to the 2-man's role in this context. Protecting the entry, securing exits, and checking for hostages focus on different strategic responsibilities during an operation rather than the immediate action of entering and clearing the room.
