you mean the one where the black ops guy has to steal the map with the location of the SCUD launcher? the third last USA mission? yeah, if you dont know how to do it its pretty frustrating ^^
if you know how to do it though, and you have a steady aim, you can win it pretty easy. all you have to do is crawl all the time till you get to the house. if you stay to the ground, i dunno if its for some weird game bug, but those russians wont see you, not even if your at their feet (well i never got THAT close but lets say 1 mt distance..). blind people

anyway, you reach the house crawling, only to find an officer outside the only entrance, and he has NV goggles, and he can spot you..
so when you get close enough, you sprint inside the house (its enough to enter it to get the map) and then you just stay prone inside the house, wait for everyone to run towards you and then you shoot em all with your MP5

. anyways, after a while a BMP or a T72 comes (cant remember). 2 choices: use the satchel charges and blow it up (had loads of fun doing that) or just run away.
this mission aint really a problem once you know what your doing, and you act like your a black ops, in other words if you see someone you dont shoot him right away. its IMPERATIVE that you dont make ANY noise until you got the plans. else its impossible, with hinds, tanks and other nasty stuff looking for you.
the mission after that is downright impossible. with a squad of 8 men, and the support of 2 cobras and 3 M1A1s (wich are radiod in as support) you have to destroy the scud launcher, surrounded by some 6 shilkas and 5 T80s and various T72s and BMPs. its near impossible. you also have to deal with 30+ soldiers wandering around, some of them spetz natzes

in the end, i snuck in alone with my LAW launcher, saw the scud, blew it up, then ran like hell towards the exit point. BOOM mission finished in 5 minutes
