if you unlock a scope on assault for the us army, it wont be there for assault on the russian army you have to unlock it again.
its been done as on bfbc2 you had all unlock by level 25 if you were good, so this is to make it last for upto 100hrs before you have everything.
I cant believe there are already level33 players out there, and probably higher.
they really should release a game like this the same day world wide.
Cheers dude, makes sense.
