As far as I know, only (relatively) recently the us armed forces began to train their soldier to get used to other countries' weapons(Like the ak, steyr,etc).And with really bad results-I have seen these trainings and let me say it:The average (standard) soldier is not able to use an AK as good as I'm able to use his M16/M4 carbine or an AR15 derivative. I'm just wondering why the american military doctrine is so focused on american weapons and ignore the rest of the world.Its troops has to face several enemies around the world, but the average american soldier simply doesn't know the enemy rifles or simply doesn't know how to operate them.Now try to imagine the following:You just run out of ammo, your only chance to get back to home alive is to use the enemy's weapons against him.But you never learnt how to use them.So what are your going to?Cry like a baby and hope the enemy will have mercy of you?! I have seen and heards so many times the other countries' military forces complaining about the fact the us soldiers have the greatest lack of knowledge concerning the small arms sector.The don't know how to load, to clean, to un-jam and sometimes even how to shoot the weapons(E.g.:How to disable the safety). Why the us government doesn't provide some extra training???
