Rules of Engagement
From Wikipedia

In military or police operations, the rules of engagement (ROE) determine when, where and how force shall be used. Such rules are both general and specific, and there have been large variations between cultures throughout history.

The rules may be made public, as in a martial law or curfew situation, but are typically only fully known to the force that intends to use them.
