If you get yourself a sherman tank in game...
Take a look at your F key on your keyboard,...
Take a good long look at it. Now imagine if you pressed that key it would select different ammo.
By Christs awesome beard, it does!
What is the single most reason you get your ass handed to you when taking on German tanks across an open plain? Well, they are better than you. They are badass, shoot straight down the barrel, punch a hole in your face - better than you. And you? You're out of range.
Use your smoke shells and fire them up in the vacinity of the enemy tank(s), from a distance you won't be able to see the confusion you caused, because to render smoke at that distance is not something your Win98 PC can handle... anyway, once you've fired a few smokes, full throttle, and soon you'll be in range to give that German tank a few punches back.
Oh, and don't forget firing AT rounds at an infantary filled trench is as effective as running up to them with your spade held high and your trousers round your ankles. Switch your god damn ammo to HE and blow the shit out of them!
