It's like guerrilla warfare. If you reveal your location, all it does is allow your opponent to improve his artillery bearings. It's better to move quietly, with stealth, under cover of night. You've got two choices: You can wear cammies and shimmy along on your belly, or you can put on a red coat and stand up for everyone to see. It comes down to whether you want to be the British army in the Revolutionary War or the Viet Cong. History tells us which tactic was more effective.
