Why Are The Russians So Tough?

I tried to kick some coalition rogues' butts through mission in Sovetskaya bar, but I ended up being kicked in the balls instead. Why are those guys soo tough I did not even last five seconds? I observe the difficulty level about 35 to 46. Seriously? Anybody here survived this type of missions is a KING Is there any bar missions in Altair space l can enjoy, about level 25? My piloting and combat skill sucks
