"What a gang of apes!" he growled. "Maybe if you'd all buy it this drop, they could start over and build the kind of outfit the Lieutenant expected you to be. But probably not with the sort of recruits they get these days."

He suddenly straightened up, shouted, "I want to remind you that each and every one of you has cost the gov'ment, counting weapons, armor, ammo, instrumentation, and training, everything, including the way you overeat has cost, on the hoof, better'n half a million. Add in the thirty cents you are actually worth and that runs to quite a sum." He glared at us. "So bring it back! We can spare you, but we can't spare that fancy suit you're wearing. I don't want any heroes in this outfit; the Lieutenant wouldn't like it. You got a job to do, you go down, you do it, you keep your ears open for recall, you show up for retrieval on the bounce and by the numbers. Got it?"

--"Starship Troopers" by Robert A. Heinlein

In the book, the suits were armored to the point that anything that killed the wearer was very likely to have wrecked the suit first. There weren't any "jinxed" suits, but there was another part of the book where cadet pips that were worn (by tradition) by many cadets often had casualties attached to them, sometimes to the point of being "jinxed."

I could see a "casualty suit" being reused as a matter of pure logic, but if I were running the Army, such suits would probably be broken down for parts and distributed anonymously among many others. The idea of wearing an armored suit somebody had died in is much more personal than, for example, driving a repaired tank that somebody had been killed in.
