Missiles typically have some 93% of reliability according to E.Fleeman's Tactical Missile Design book. and US sent some 5000. 350 among those is expected to be dud. Which might be the one delivered to the poor guy's unit.
But of course age of the stock might impact reliability. Thus there is concept of "guaranteed life" where the missile is expected to be fully functional in that timeline. e.g 10 years before needing overhaul or life extension. Beyond that, reliability decreases. The missile may still be usable but well its probability of failure increase.
