Which tool combination is generally considered highly effective for forcible entry?

The combination of a flat-head axe and Halligan tool is recognized as highly effective for forcible entry due to the unique capabilities of each tool. The flat-head axe is a versatile tool used for striking and breaching, while the Halligan tool has prying, twisting, and striking functionalities that make it an essential device for creating gaps in doors and windows.

When these tools are used together, the flat-head axe can be used to deliver powerful strikes that aid in breaking through barriers, while the Halligan's forked end can be inserted into the gap created by the axe to further pry open the door, providing firefighters with a reliable and efficient means to gain access to a structure. This synergy allows for a combination of striking and prying methods that can quickly overcome various types of locks and barriers encountered during emergency situations.

Other combinations, such as a chainsaw with a fire extinguisher or a cutting torch with a sledgehammer, may not provide the same level of accessibility and efficiency needed for forcible entry.
