You can transfer these problem to the devs.
I notice the gun from M60 he have problem with the degrees this tank he have a big size and high turret, the gun he cant look down the enemy tracks and you cant shoot him all these in the stable stage floor,
when you have even a small hill you cant shot your enemy, you cant see the enemy tank only the enemy cap and if the enemy move left-right you cant shot,
this with the normal tanks with high turret and big size, when you have object140 enemy, mars15,chatillon25t,T28,t-55,cy-122-54,is7 you cant shot the enemys with the wrong degrees from the tank all these in a stable floor, i dont talk in a high level floor, you cant see the enemy!!!
Many tanks they have the same degrees but they have low size so they can see down with the little size. Like the object 140 the gun he do not go down but he is a low size tank same with the mars15, the FV4030 , t-55 and all the low size tanks. For the big size tanks like M60 he dont have any degrees to see low down the enemy in the stable floor.
That why i talk in my topics when you do something new in tank you need first to test it. It has been a month since we take the m60 from roulette and this tank he have big problem with the gun, also when you go to climp on the hill or an easy high floor your tank stop and he cant move, also when someone touches your tank he block you and you cant move. All the tanks with high turret they have the ability the gun to see down the enemy tracks from close distance.
