Oh dear. It's the "meaning of the word" again!
Actually, John Galt himself said in his three-hour long radio speech (which didn't need to be that long, I think) that if a man dies fighting for his country it's not a sacrifice. But, as I've said before, to each his own.

if a man dies fighting for his country it's not a sacrifice.

This is consistent with the philosophy. More pointedly, it's a value judgement.

When Rand talked of sacrifice she meant the surrender of a value for the sake of a lesser value or nonvalue. If a man values his country more than his life, it is indeed, not a sacrifice. Jumping on a grenade to save your buddy is a sacrifice.
