I suspect that the folks taking a Farnam class are a lot different from your average squad of grunts.Maybe the military should train them properly.
Every Farnam class that I've attended has been run with a hot range, and there wasn't one ND ever.
Now I get that the average shoot attracts a lot of newbies, and Elmers, whose grasp of firearm safety is imaginary at best, but if you have trained people in a class or on a military base, it's far safer to run a hot range / base where the guns are always loaded, than it is to mess around with a ton of handling, loading, unloading, inspecting, etc.
A friend of mine was in the 101st during the Iraq Invasion. One of the idiots in his squad decided to clean his rifle without clearing it. He managed to shoot another squad mate. The fellow who was shot was sent to Ramstein for treatment. The shooter was also sent out of country because he was having trouble walking -- the remaining members of the squad had decided to give him some percussive retraining.
