The correct way to use scout early game is mainly running up to the enemy's forward barracks sabotaging it then running inside trying to kill as many infantry units as possible this will make the barracks easier to kill due to it being at half health. Also it makes the infantry easier to kill due to them all now spawning with half health.

In no situation should you be using the ranged rifle as scout i suggest using the close range SMG. Also scout does have a infantry bullet resist making him able to take more shots than other classes.

Scout should always be on the front line sabotaging buildings, killing infantry and finally sticky stunning enemy tanks. In no circumstance should a scout be using hide to sneak around the map it just wastes valuable time. Neither should a scout use the ranged rifle.

late game you mainly need to be getting into a jeep with a engineer going round the map and killing buildings and refinery's. You can also use sticky stun's to disable heavy tanks later on in the game, this will render them unable to move for a short period of time so it is much easier for your team to kill.

Also you can kill turrets by sabotaging them they will be disabled after you sabotage them, after this they will die after a short amount of time. And off course scout is good for sticking the enemy commander for a ninja.

The close range smg is the primary weapon for scout and is very easy to use due to it being a spray and pray weapon. It has a decent rate of fire decent damage and is very easy to use.

The Shotgun is good also however you have to be very close to your enemy to kill them. It can kill on one shot if you land all of your hits at very close range.

The first Skill you should use a scout is speed upgrade. The skills i use as scout are mainly speed upgrade, health upgrade, accuracy upgrade and ammo upgrade. Another skill that is good for scout is melee upgrade for running inside there barracks and killing infantry with melee.

The scout can be a very effective class if you learn to play him correctly. However the scout is still situational and should not be played constantly throughout the match
