ABSTRACT:
A forcible entry tool is disclosed which enables law enforcement personnel such as SWAT or police or other persons such as firemen to breach a heavily fortified door or the like in a matter of seconds without the use of explosives. A ram like device is taught which is normally operated by two persons which can penetrate through a steel re-enforced door by using a heavy-duty slide hammer with a leg support that is locked to the correct height for support when a pin is pulled. The apparatus also has a hook on one end which may be impaled in the door or hooked to any other object and the door or object removed outwardly.
