A live-fire exercise or LFX is any military exercise in which a realistic scenario for the use of specific equipment is demonstrated. In the popular lexicon this is applied primarily to tests of weapons or weapon systems that are associated with the various branches of a nation's armed forces, although the term can be applied to the civilian arena as well.
