Your stretching pulls the word over so large an area as to render it almost meaningless. I feel as though it exists to further some other goal.

The last time I heard art defined, it was as "something which has additional layers of meaning beyond the plain interpretation", or something like that. I'm not sure even that's accurate.

However, if you're going to insist on calling a spec ops team in action "art", then that level of stretching is such that so could designing a diesel locomotive, or any number of other purely practical exercises which are not performed for their aesthetic value. A "found object", or Jackson Pollock painting, or what-have-you, is created primarily for aesthetic value and/or communication of additional layers of meaning.
