ABSTRACT:
A forcible entry tool is disclosed which enables law enforcement personnel such as SWAT teams or police or other persons such as fireman to breach a heavily fortified door or the like in a matter of seconds without the use of explosives. A ram is taught which is adjustable in weight to suit the needs of an individual and which may be inter-locked with another ram of the same structure in order to "gang" them and several can be locked together, forming a heavy, multi-manned battering ram.
