Directives issued by military authority specifying the circumstances, conditions, degree, and manner in which force, or actions which could be perceived as hostile, may be applied.

These are specific, often highly detailed, instructions that govern how military personnel can use force in a given operational area. They are crucial for maintaining discipline and adhering to international law.

The story behind the word. The phrase 'Rules of Engagement' is a modern military and legal term that emerged in the mid-20th century, particularly gaining prominence during the Cold War and subsequent conflicts. It's a straightforward combination of 'rules' (from Old French 'reule', meaning 'rule, regulation') and 'engagement' (from Old French 'engagier', meaning 'to pledge, involve'), reflecting the formal directives for how military forces are to be involved in a conflict.
