regarding PJs post,

Not sure of the actual numbers, but it has been taught at various military schools in which I attended that a very large number of dead soldiers in Vietnam were found with jammed/inoperable rifles or their platoon mates had jammed/inoperable rifles. Of course, were this true it would not exactly be something the Senate Armed Forces Committee would be excited to advertise, and could also be seen as a national security issue. I dont know, maybe it was just a reason to make us clean our rifles more, kind of like the time I got smoked because my canteen cup was dirty and, according to the TAC, "dirty cups killed 1000s in vietnam" haha. I pointed out that we never use canteen cups, because our water was bottled now, he was not impressed
