Which two hallway movements are used?

• A. Single File and Double File
• B. Diagonal Entry
• C. Overlapping Sprints
• D. Side-by-Side

Answer: (A)

Moving through a hallway requires selecting a formation that fits the space while keeping the team protected and able to observe ahead. The two hallway movements you’ll see most often are single-file and double-file.

Single-file keeps everyone in one narrow line, which minimizes exposure around corners and doors, makes it easier to control the cadence, and lets the lead element clear ahead without confusion. It’s the reliable choice when the corridor is tight or when you’re approaching a likely contact area where you want maximum concealment and precise movement.

Double-file uses two personnel side by side in a wider hallway, enabling simultaneous scanning and coverage of both sides while maintaining speed. This setup allows quicker advancement and provides better mutual support if a threat is encountered, as each officer can watch a different sector and still stay connected.

In very narrow passages, single-file is preferred; in hallways wide enough to safely maintain two lines of observation and fire, double-file is appropriate. The other options describe techniques that are suited to different contexts (such as entering rooms at an angle or sprinting patterns) and aren’t the standard hallway formations.
