Minecraft wiki entry for Player_versus_Player, associated text: While most of your allies are fighting the enemy melee (better if there aren't many troops on each side), the classic styled sniper (which have very powerful bows) can fire a precise shot which will do good damage while the enemy cannot retaliate much due to your allies attacking them with a sword. Be sure not to hit the ally though. One may drink invisibility potions so even if the enemy noticed the shot and want to hit the sniper first, they cannot shoot the sniper.
