I'd bet you'd be among the first screaming for heads when some LCpl gets a burst in his torso because some numb nuts mistakenly put live rounds in his rifle during MOUT. I can hear it now: "What idiot gave live rounds to troops firing at each other in a training exercise? Whomever ordered that was negligent and should be prosecuted!"
There's a difference between reading books about the military and knowing how troops actually operate in the field. There is one unalterable truth about every military operation: troops and officers will make bad decisions and screw up. Anyone who thinks otherwise is living in some computer-game/internet fanciful world that bears no relation to reality.
The USS Cole; Kohlbar Towers; Afghanistan War; Al Queda....
Please stop me when you figure out that the area is a danger zone.
Wake up......damn marines. :>)
