The Skeet shot fires three small disks into the air, and in the middle of its flight, similar to when the "payload" drops its payload, your tank will shoot 3 shoots at the disks which will break shattering them into 5 pieces each dealing 10 damage and a small explosion. The Shots follow a similar pattern to the triple shot.
The disks will not break unless they are still in the air and there is a direct line of sight between you and the disks.
Note if the disks hit another tank before they are broken they will deal 10 damage and there will not be an explosion.
When you have an open field and several enemys in front of you and you are on a higher position as them, you can fire the skeets with 1 degree angle so their highest destination will be imidiately reached you your tank will instantlay shoot them so the spread isnt as high as if they would be shatterd up in the air but with an angle that is higher than 45 and strength that is under 50 you will have the least spread, but the opponent has to be near you so you can hit him.
It is way better against larger groups of enemies than against one.
