I have heard this yet.
It really is amazing (not just for U.S. military, but any that mobilizes) that there are as few injuries/deaths as there are. So many people mobilizing with some of the world's most dangerous weapons in horrible conditions, usually at night, driving/walking/flying while under fire or threat of fire, and there are only rare instances of accidents.
Just shows you the training/coordination that goes into these maneuvers. I've been in awe of this since my days in the service.
