Well, you could have a small snipe off on Convoy in BO1.
Well now I feel stupid as I wasnt bragging. I just saw a lot of comments about how people cant pwn with snipers, and I feel its the easiest thing to do.
TDM is kind of easy to use snipers in. Objective modes is a little harder. It all depends on how good you are at controlling the engagements and keeping a good distance that you can pull up you sniper and kill the enemy before he can you.
