I unlocked the Sniper Rifle first. Even though I mostly had been playing a Medic in BF2. I always liked playing a sniper in BF42, and the Desert Combat mods (usually because my clanmates had the other choices covered well). The .50Cal sniper rifle has one of the nicest sounds, but the damage it does isn't that 'great'. It is not the 'one shot, one kill' weapon it mostly was, but still much more fun then the regular one. The trade-off being the reduced ammo capacity (IIRC). I think I will unlock the medic next time.
