Currently , I made some major updates.
They are :

1.Added stab for moving the turret left or right side so body will move and turret will stay stable where you focused

2.Added scope that comes outside of the tank so you have just to zoom and you see the target and you dont have to go 3d view to see if youre aiming correct.

3.Added manpulator that actually is real. This manipulator turns the turret L or R side and even moves gun up and down.

4.Decreased inside shape of the gun so it looks like real

5.Added stab for aiming

6.Added new armour on the turret so it doesnt look so ugly

7.Added wing gun (machine gun) for destroying infantry and etc.

8.Gun has a recoil

Notes

1.New armour should move free while youre moving but I cant proove it because I havent finished tracks

2.Gun is not accurate because basically it is turned off and you have to activate AG4 to make the stab work.

3.You have to wait after you shoot because it has recoil and you have to wait about 1-2 seconds.
