How come the U.S. Army cant beat some religious fanatics that are using home-made bombs, RPGs and Ak47s/74s?
This is serious question.
ok, I'll try and give a serious answer.
since they (the fanatics) aren't 'regular army', so they have no baracks, bases, supply lines, suport structure, or government with an adress. at least not in the normal sense of the word. so when they aren't shooting at you and the guns are under their robes they are fairly hard to distinguish from the arab who is on your side (if their are any).
so do to the above they get to pick the time and place of the confrontation, and they are going to pick times and places that give them the advantage. if they set up a situation and it all of a sudden doesn't look good for them, then they just skip-it and wait for another day.
meanwhile our guys have to go around presenting themselves as a tartget and rarely get to engage until they've drawn fire.
