"Forcible entry" is a joint military operation conducted against armed opposition to gain entry into the territory of an adversary by seizing a lodgment as rapidly as possible in order to enable the conduct of follow-in operations or conduct a singular operation. A lodgment is a designated area in a hostile or potentially hostile territory that, when seized and held, makes the continuous landing of troops and materiel possible and provides maneuver space for subsequent operations (a lodgment may be an airhead, a beachhead, or a combination thereof). Lodgment requirements depend upon the objective(s) of the overall operation or larger campaign. A lodgment may have established facilities and infrastructure. Forcible entry planning must consider the political, military, economic, social, informational, and infrastructure realities. This publication provides joint doctrine for planning, executing, and assessing joint forcible entry operations. This publication has been prepared under the direction of the Chairman of the Joint Chiefs of Staff. It sets forth joint doctrine to govern the activities and performance of the Armed Forces of the United States in joint operations and provides the doctrinal basis for interagency coordination and for US military involvement in multinational operations. It provides military guidance for the exercise of authority by combatant commanders and other joint force commanders (JFCs) and prescribes joint doctrine for operations, education, and training. It provides military guidance for use by the Armed Forces in preparing their appropriate plans.
