Rules of engagement (ROE) are guidelines that dictate how military forces can interact with enemy forces during conflicts. They establish the conditions under which troops can use force, ensuring that actions are lawful and appropriate. ROE help prevent unnecessary escalation and protect civilians by outlining when and how to engage in combat. These rules can vary based on the mission, location, and specific circumstances. They are designed to balance military objectives with legal and ethical considerations, ensuring that actions align with international laws, such as those outlined in the Geneva Conventions. Understanding ROE is crucial for maintaining discipline and accountability in military operations.
