Sniper

Snipers are a type of weapon that can severely cripple your opponent, if used correctly.

Main use
Snipers are used to destroy exposed weapons. They can destroy most weapons in only one shot, because of the high damage bonus applied on weapons, the only exceptions being heavy rocket, 20mm cannon, cannon, firebeam, plasma laser and missile silos, that are destroyed in 2 shots (cannon 3 shots, missile silos 4 shots).

They are extremely accurate, by having a very low spread, even on very large maps. This means a good enough player can easily achieve door snipes: destroying a weapon while it is firing, or while the door is opened.

Other uses
Snipers can be upgraded into AP snipers, which penetrate 1 layer of armor or 1 door before de-spawning.

Snipers are a necessity to paint target for missile silos : the silo by itself can't be fired, the sniper will gain a laser sight while painting the target for the missiles. Some players call this "point and click".

Eagle eye gives this same laser sight to all your snipers, it starts as a horizontal line but can be adjusted with page up/page down to match the drop caused by gravity. This process is manual, but lets you be perfectly accurate on all your shots afterwards.
