Wait til the next patch is released, very soon...
Amongst other things, it's removing the ability to fire while jumping, it's very much so slowing down the process of going to prone (so there's a delay until you can fire again)...
You'll also be able to SEE the UAV satellite (and destroy it), and assault-class grenade launchers now allow you to bounce the grenades off walls. Oh, and it also opens up the two new unlocks we've been expecting...
Anti-Tank (secondary weapon):
FN P90 (Stargate SG-1 fans may recognise this...)
Sniper (primary weapon):
L96A1 (.308-cal bolt-action)
