Sometimes sniping the other team gets preoccupied with taking you out beyond all other targets - its a great sign that you're doing well, but it can spell disaster for the rest of the day. You have to behave a little differently to snipe successfully when the other team is actively trying to find you, and has you on their mind. These are some tips that might help:

1) Choice of cover: When there is an obviously excellent piece of cover, a fallen log, etc, pick something else where you can cover the obvious spot. If they're looking for you, they'll try to think like you, and figure out the best spot *they* would snipe from - meaning every-time they see a fallen log they'll pay it allot of extra attention, and give less attention to things in its vicinity. Don't bother with "hard cover" which would protect you from BBs, its obvious, and when the enemy are sweeping for you, they'll pin your behind it and flank you. Pick somewhere in-obvious, preferably overshadowed by something really obvious. Its allot of fun to watch people advance on what they think your position is, and advance *right past you*.

2) Choice of camouflage: A) Don't put your ghillie suit on in sight of the other team. Wear simple BDUs and keep it in a bag, put it on when your out of sight - don't let them know what they should be looking for! B) Additionally, once they've hit you a few times, change to a different pattern ghillie, or change to BDUs, don't let your ghillie become a liability as you get "field famous" - you can use it as bait as well, later into the game.

3) Choice of tactics: Instead of lone-wolfing it, or going it with just your spotter, try moving 100-200 ft behind a large group of teammates, when they engage they'll have the enemies full attention, fall back and try to flank the battle. Alternatively, keep track of where your team is, get yourself "spotted" with an amateurish shot, etc, and fall back to the group as bait.

4) Choice of weapons: If you've got something support-esque, or at least full-auto switch to that and ghillie-wrap it so that it isn't obvious. If you've been going bolt action in the rest of the game, when the enemy spots you they'll focus on closing the distance as fast as possible, and be unprepared for you to hit back with similar firepower.

Good luck! Sniping when everyone on the other team wants a piece of you is harder, more exciting, and you can take your infamy as a compliment.
