The Commando Order was issued by the OKW, the high command of the German Armed Forces, on 18 October 1942. This order stated that all Allied commandos captured in Europe and Africa should be summarily executed without trial, even if in proper uniforms or if they attempted to surrender. Any commando or small group of commandos or a similar unit, agents, and saboteurs not in proper uniforms who fell into the hands of the German forces by some means other than direct combat, were to be handed over immediately to the Sicherheitsdienst for immediate execution.

In civil and military jurisprudence, summary execution is the putting to death of a person accused of a crime without the benefit of a free and fair trial. The term results from the legal concept of summary justice to punish a summary offense, as in the case of a drumhead court-martial, but the term usually denotes the summary execution of a sentence of death. Under international law, it is a combatant's refusal to accept an opponent's lawful surrender and the combatant's provision of no quarter, by killing the surrendering opponents.
