We picked up hors de combat directly from French back in the mid-18th century. Benjamin Franklin put the term to use in a 1776 letter, observing that an "arrow sticking in any part of a man puts him hors du [sic] combat till it is extracted." But you don't have to use the word as literally as Franklin did. Combat can refer to any fight or contest, not just fighting in a war. A politician who's out of the running in a political race could be declared "hors de combat," for example. But the adjective (or adverb) need not refer only to humans or animals: if you own a car, chances are your vehicle has been hors de combat at least once.
