Tank vs tank and why I always lose

[Parkaboy]

Ok so I'm getting abit wee'ed off with constantly missing shots with Tank vs Tank action.

I spot tank fire at treads, miss

tank turns to target my tank

I shoot at treads again, miss

tank shoots at my treads, hits

I now have 2 options turret of barrel,

but it matters little as in or out of direct control I miss and my turret is or hull is smashed.

It's happens way too often to be down to chance I've got the white dot aimed at the enemy tank. So why do they hit and I miss most of the time when I play Germany most of the time?
