White Flag Tactic, Shadowgun: DeadZone
Based on distraction and deception, the white flag tactic is often used by a team of snipers in a sniper vs sniper battle.
The White Flag tactic can easily distract and deceive novice enemy snipers. While you and your sniper team mate(s) are crouched behind cover, one of you will raise the Flag by using the Quick Command with the Flag symbol.
Enemy snipers will be distracted by the flag because they know that someone is below that command bubble. Use the flag a few times and move around a tiny bit while still maintaining cover. By this time the enemy snipers will probably think you're a noob that doesn't know they can see your command bubble.
Now tap and release the fire button and you'll pop up from cover and duck back again. The enemy snipers will eagerly break cover to fire at you. And your teammates use that opportunity to take them out.
