In warfare, ramming is a technique used in air, sea, and land combat. The term originated from battering ram, a siege engine used to bring down fortifications by hitting it with the force of the ram's momentum, and ultimately from male sheep. Thus, in warfare, ramming refers to hitting a target by running oneself into the target.
Today, hand-held battering rams are one tool among many used by law enforcement and military personnel for door breaching.[1] Forcible entry by criminals has been implemented using such methods as vehicles rammed into buildings.[2]
