Jeepers... I love them all... not just military arms, but pretty much everything. I have 2 AR's (and this is after the whole basic training 100:1 ratio of cleaning the piece to actually firing the thing....
) I think it's a fine firearm, not necessarily something remembered from the Army. Levers, pumps, bolts... semi-autos and revolvers.... I have them.
As far as military pattern rifles, I guess I prefer them over most... they make sense to me, are fun to shoot and easy to reload for and find relatively inexpensive ammo. In addition to my 2 AR's, I have an M1a and an M1 (and would have a Springfield, a Thompson, and an M1 Carbine if I could afford one.) I also like lever-actions, the 2nd most prolific arm in my safe. I've never been into Commie-block arms... at all, nor into the earlier foreign bolt-action military stuff (Mosin, K98, Krag, SMLE, etc) I guess part of that is I don't hunt, I consider myself a 'pratical' shooter. I like to shoot just to shoot, sometimes... sort of like a Sunday motorcycle drive, riding just to ride.
I feel for you guys that now abhor things you experienced in the military, the only thing I can relate to that is NBC... I absolutely HATED anything related to NBC (all the time understanding that it was necessary.) We had stupid non-coms and officers, it is just like that in civilian life, too (just work in any office,) so I don't think that was exclusive to the military.
