Protective signs are legally protected symbols to be used during an armed conflict to mark persons and objects under the protection of various treaties of international humanitarian law. While their essential meaning can be summarized as "don't shoot" or "don't attack", the exact conditions implied vary depending on the respective sign and the circumstances of its use. The form, shape and color of these signs are defined by the rules of international humanitarian law. Usually, they are easy to draw in order to make even an improvised use as easy as possible, and they were chosen to be as concise, recognizable and visible as possible under all circumstances. The misuse of protective signs is a violation of international humanitarian law and punishable under the national law of all countries who are state parties to the respective treaties. Using protective signs in order to injure, kill, or capture the enemy (perfidy) is a war crime.
