Tactics: Assault

I suggest the M4A1 with red dot sight and grnade launcher. And akimbo mp9. Or MG36 with overkill and M4A1 as secondary.

Tactics:Snipers

The best class i would say is MSR with heartbeat and extended mags. Secondary would be akimbo fmg9's. do perk as dead silence steady aim and assaisin all pro. claymore and port radar. use support.
