Guns

All aircraft have main guns, though each carries a different amount of ammo by default and the A-10A and Su-25 have slightly different damages. Light fighter bombers, the NATO F-16 and PACT MiG-29, start with 120 rounds, close air support aircraft, the NATO A-10 and PACT Su-25, get 200 rounds, and the air superiority class of aircraft, the NATO F-15 and PACT Su-27, have 150 rounds.

The damage of the main guns actually has some variation between aircraft. the light fighter bomber and air supremacy classes share the same damage of 20, but the A-10 and Su-25 do differing amounts. The A-10 with still do 20 to aircraft, but that will be buffed up to 40 when attacking ground units, while the Su-25 will simply do 24 damage to air targets.

To target a creep it is best to slow down and line yourself up with that creep. There is no need to worry about the pitch of your aircraft as the gun seems to be able to shoot down at creeps provided you maintain enough distance to the creep you are targeting, and the inclination of the shots will adjust as you approach so that you can still hit the creep.

The upgrades for the guns are as follow:
 * High Explosive Bullets: Increases the gun damage by 15%.
 * Extra Ammo: Gives 80 extra round for the gun.
