nsc and enemys pick up any weapon, i have seen that for sure. and if i am not misttaken it is writen down in the booklet of the game as a warning...
as for conquering hostile cities:
i have done so out of mischief or amusement numerous times.
here are some of my strategies:
first find a secure area where you have good sight but your oponent doesent. meaning in short house fights!!!!
the KI is to dumb and also you get much better work out of grenades when fighting inside...
to do so i try to get my squad generaly inside a bar. the bars are all built the same. i position only my team on the ground lvl because when it gets to achieving unrealistic headshots the enemy is alwas better... and on the first floor the oponent can only see your head when you are crouching...
on the groundfloor i position mostly two soldiers at the rear entrance facing the door and being not seen through any windows. normaly windows are not seethrouable by the enemy but the get smashed sometimes...
one soldier is locatet at the toilet as backup for my other soldier located in the main bar room. if i got more soldiers than i put them in the Corridor that leads outside the main bar room. the guy in the main room is my char, also my main fighter. after every one is in their position and secure i await the incoming enemy. they will! get into a sloughterhouse. works always infailable.
after the initial wave of suiciders is drained he (main char) gets out hunting. i prefer silenced weapons for this. all german weapons (HK XY) are good for that early in the game. if you face more than one enemy together be sure to kill firstly the one thats facing you with a claer headshot. the other one wont be bewildered most times, also if he is alarmed then he still has to turn around and thats costing allot time for him...
one a side note: if posssible and my weaponry allows for it: a fight in a hostile city is far easier if you are on your own. the more mebers you have in your team the more you have to control. so if you plan to attack a hostile city then go alone. and as r@s says save often^^
hope i could help.....
