Arica Harbour is my fav normally i use Gol for recon, all round good sniper weapon, Mortar strikes are pretty usefull to distroy enemy holdouts, but camping in the same spot your more likely to get killed, always move from one spot to another, it confuses the opposing team sniper, thinking that you are in the same spot. I normally see how the team is doing before choosing my class. If we have taken A,B,C you can rank up on higher kills with sniper and flank them, however if we are losing and only have point A/B better to be a Assult or Medic.
