Fanboism at its best.
Sorry that i have to be so rude but are you even thinking before you say something ?
Doesnt seem so,if you arent a noob and you got some experience with the OH sniper you cant lose it.
When you lose it its only your fault : m20 - grens close to sniper,clown car - gren - mortar ? - cant even kill with one shot on his head ,what else do you have ?
Its not possible to always be cautious but if grens or hmg cover your rears ,you will see the enemy early enough to move your sniper on a safer retreat route.
Try to arguement
But it is the same with the soviet sniper. The OH-Sniper has much health and the soviet onea is a two-men-sniperteam. So I guess the survivability is pretty much the same.
