[2] These enemy targets can be planes, helicopters, trains, ships and sea mines in World War II,[2] which later also include cruise missiles and drones in subsequent conflicts.[3] The manner of destruction that qualify for a victory mark also varies, from bombs and cannons by planes, deck guns by ships to torpedoes by submarines.[2] In 2012, a German Eurofighter was spotted with a kill mark denoting a simulated victory over a U.S. Air Force F-22 Raptor, achieved in a dogfight during a training exercise.[4] In the United States Air Force, as of 2010, victory markings are applied in the form of six inch green stars set within a black border with the type of aircraft defeated stencilled inside the star in white lettering.[5] In the Russo-Ukrainian War, Ukrainian anti-air defenses such as Flakpanzer Gepards and Patriot Missile systems are decorated with victory markings for successfully shooting down Russian aerial targets, missiles and Iranian Shahed drones.
