I don't have a problem with that...at all.In BCT I just about soiled myself the night we crawled under barbed wire with an M-60 being fired over our heads.They told us they were live rounds and I believed them...at the time,at least.Today I recognize that for safety reasons they probably wouldn't have fired live rounds but,instead,they just wanted us to *believe* it.
I still remember the tracers going overhead....almost 50 years later.
They were live rounds. Just fired at an elevation of 12 feet over the ground. You could have stood up and jumped and not have gotten hit. But scary no matter what.
