Self-defense Definition from Government Dictionaries & Glossaries
DOD Dictionary of Military Terms
A commander has the authority and obligation to use all necessary means available and to take all appropriate action to defend that commander’s unit and other US forces in the vicinity from a hostile act or hostile intent. Force used should not exceed that which is necessary to decisively counter the hostile act or intent and ensure the continued safety of US forces or other persons and property they are ordered to protect. US forces may employ such force in self-defense only so long as the hostile force continues to present an imminent threat.
