PKM is a great weapon, SVD, Type 88 and L96A1 are the snipers which are good over distance.
M95, if you actually want to get a jet.
Aim for body not head
There IS bullet drop on BF2..so aim slightly above head for headshots..
Play servers with less than 50 ping or dont bother sniping.
actually no. I have more reaction speed when I have all my keys mapped onto a PS2 controller. Sometimes though the analog sticks drag, like I will constantly be looking down because it keeps pushing me down.
