Hmmm...
it depends on a map or normal/HC mode, but so far these are my favoute guns:
Assault class: hk416 (normal mode) / m16 or An94 (HC mode)
Medic: m60
Engineer: AKS 74U or Saiga
Recon: M95 or SVU
Sidearm: undecided
RPG's: C.Gustav against infantry / AT4 as anti-vehicle (but overall all of them lack of power against tanks )
As regard to EAforum debate on M60, I don't care what they gona do with it. 4 me it is fine as it is, although in a duel situation between M60 or anyother gun, M60 wins most of the time.
