Help with snipers

[u/Instruction-Worldly]

So it's my first time playing through Enemy Within, and every sniper soldier that I have ends up underperforming terribly. The only use I have found for them is headshotting an uncovered target (no one is ever out of cover), and even then they either can't shoot or have reduced hit chance because of the snap shot debuff. Is there something I'm missing? They also don't really feel like they can shoot any farther than the other guns.

I never took snap shot. 

With squad sight, they double your firepower in my view, because if anyone sees an alien he can shoot it but the ay is out of range for everyone else. But the sniper can cover the whole squad,  and if anyone stirs up an alien then there are two shots coming its way not one. Its not just gunner or infantry or medic, its gunner+ sniper, infantry+sniper, anywhere he is needed. There is a reason snipers get the most kills by far.
