Which term refers to the phase that enforces lawful entry under 18 USC 3109?

• A. Breach phase
• B. Containment phase
• C. Clear phase
• D. Occupant Control

Answer: (A)

Forcible entry into a structure to execute a warrant or arrest is described by the breach phase. This phase specifically captures the moment officers use reasonable force to gain access under 18 U.S.C. 3109, which authorizes breaking and entering when necessary to carry out a lawful warrant or arrest. The breach phase is the entry action itself, distinct from what happens after entry. Containment focuses on securing the perimeter and preventing escape, the clear phase involves searching and ensuring the interior is safe, and occupant control deals with directing people inside. Since the question asks about the phase that enforces lawful entry, the breach phase best fits that role.
