There is one: An ambush that starts inside the enemy camp at night. That requires infiltration skills though, so only Special Forces stand a solid chance of success. And you wind up in the middle of a clusterfuck no matter how it goes. The first recorded success was with a very special set of Special Forces, the men who sailed with Odysseus to Troy. And they infiltrated inside of a giant wooden horse statue that the Trojans themselves dragged through the city gates.
