Try running forward while adopting a semi-fetal position, keeping your eye's tightly closed and your marker raised above the level of your head. Point the barrel in the general direction of the bad guys, and pull the trigger as often as you can while running. If you reach your next cover intact, keep your gun up over your head and continue to shoot for 3-4 seconds, just to be sure. Once settled-in, look up over your bunker and see if any opposing players happen to be leaving the field. If they are, claim these kills in the loudest voice possible, and let out a cowboy-style 'yeehaaa". Not only will this help you claim many more kills, it will also make you extremnely popular with your fellow players at both ends of the field. Enjoy.
