Looted
Looted items are equipment or vehicles used by Orks that were created by other races. They acquire this technology either as battlefield salvage or outright theft. The looted object is often made orky, by sticking pointy bits and pieces on it.
This used to be represented in the tabletop game by allowing you to purchase vehicles from the Space Marines and Imperial Guard codexes to use in your ork army as long as you made the vehicle look like it had been modified by orks. This wasn't just a principle thing, the rulebook literally said that you had to make the vehicle look orky so no Proxies allowed. However, the vehicle always had to make use of the Orks Ballistic Skill 2 - no matter what codex the vehicle came from - at exactly the same price so unless you had good luck a ork looted vehicle would lose to its non-looted equivalent in a firefight. You also had to deal with the risk of the vehicle breaking down at the beginning of the game on a D6 roll of 1.
In the later codexs the use of looted vehicles was replaced with the use of proxies. The only part of it that remained was the Looted Wagon, a Rhino with a more forgiving rule to represent it not being made by orks. In the case of other vehicles you would have to have it count as a different vehicle in the ork codex.
