dod directive 5240.01  for the military, the use of lethal force is authorized under specific circumstances, usually governed by the rules of engagement (roes) and self-defense policies. while dod directive 5240.01 addresses intelligence activities, the use of lethal force in military contexts typically aligns with these broader principles: 1. self-defense: military personnel may use lethal force in defense of themselves or others if they are facing an imminent threat of death or serious bodily harm. 2. mission accomplishment: lethal force may be authorized to achieve a specific military objective when other means are ineffective or inappropriate. 3. hostile intent/act: when an individual or group demonstrates hostile intent (preparing to attack) or engages in a hostile act (an actual attack), lethal force may be used to neutralize the threat. 4. national security: in some cases, lethal force is authorized to protect national security interests, which could include operations against identified combatants, terrorists, or other high-level threats. 5. escalation of force (eof): lethal force may be part of a structured response after lower levels of force (warnings, non-lethal measures) have been attempted and proven ineffective. 6. declared wars/conflicts: in declared military conflicts or during active hostilities, the use of lethal force is often governed by the laws of war, including the geneva conventions, as well as established roes specific to the conflict.
