During the "Armor Wars" storyline, Justin Hammer had Tony Stark's Iron Man technology stolen by Spymaster and sold it to a number of superhumans who wore powered armor (including Stilt-Man, the Raiders, the Mauler, Beetle, Crimson Dynamo and the Titanium Man).
The General Dynamics MIM-46 Mauler was a self-propelled anti-aircraft missile system designed to a late 1950s US Army requirement for a system to combat low-flying high-performance tactical fighters and short-range ballistic missiles.
