Is It Impossible to Pen Some Tanks?

TeriyakiTanker:  Unfortunately you are way out of your league at that level.  You will face a lot less frustration if you go back to tier V and VI and work on developing your crews as well as getting comfortable with the game.  I already know you aren't going to listen but it is pretty obvious from your posts that you are not only having a hard time learning the game but you are not having much fun either. You don't need to memorize individual tank weak spots unless you are having a specific problem.  All you need to know is that frontal weak spots tend to be lower front plates, cupolas (those are the commanders and gunners hatches on top of the tank if you don't know), and sometimes machine gun ports.  Other than that sides and rears of tanks are usually good to shoot at also with some exceptions. Lastly the T110E5 isn't really a heavy and you will probably have better games if you work with the mediums and try your hardest to find hull down spots to work.  Go with the heavies and you will invariably find the real heavies in this game.
