Way back when I was in the service, this E-7 decided to conduct an impromptu weapons familiarization class in one of a base technical school's classrooms. He was a technical instructor at the school and wanted to start a activity marksmanship team. This E-7's shooting and mental skills were shaky at best.
On this fateful day he gathered five students and laid out all the necessary gear and equipment they would need for competing in High Powered Rifle tournaments - including M-14 rifles. He then drew a black marker dot on a whiteboard as a simulated target for dry firing practice. Said E-7 then proceeded to instruct these nuggets on how to properly load an M-14 magazine and charge the weapon by using a bunch of dummy rounds of his own creation. Needless to say, our hapless E-7 actually got a live 7.62 round mixed into his lot of special dummy cartridges. He then loads this magazine with what he thinks are all dummy rounds into the rifle, and proceeds to demonstrate the proper techniques of off-hand shooting. BOOM! The discharged round goes through the walls of two adjoining classrooms, both full of students, and finally stops when it hit a piece of electronic test equipment. All his students were wide-eyed, and so were all the ones in the affected classrooms and pretty much the whole building. Luckily no one was injured in this fool hardy incident but unfortunately the innocent piece of test equipment did not survive the wounds it sustained.
I was ironically instructing a class out on the small arms range for the entire security department, when the base Chief of Police arrives to tell me the story of the incident. "Hey, you'll never guess what E-7 Numbnutts just did?" The Chief could barely contain himself, "He just shot a hole in three classrooms full of students over at the ****** technical school!" He then chortled to me, "The funniest thing about it was, he drew himself a target up on the board - and missed it!"
A Board of Inquiry was held. Poor E-7 Not-so-bright did suffer consequences for his unauthorized little marksmanship class, while not separated for malfeasance, he was Article 15'd, deemed culpable for the incident, and had to personally pay for all repairs to the dearly departed electronic test instrument. Luckily he had enough time toward retirement and once his obligation to the service was paid-in-full, he was "quietly" retired.
The moral to the story was this... "No unauthorized marksmanship classes should be conducted in habited areas," and, "Be sure all your dummy rounds are indeed approved inert teaching aids!
