I wouldn't call 3 Osttruppen spam.
Apfelsaft build 2 Osttruppen into munitions cache, which means two things:
1. The fastest flame ht you can ever imagine. Guards don't come out fast enough, so the soviet player is forced to go AT nades with AT guns. You win or loose with the success of the flame ht, because...
2. ...you don't have the infantry to cap the whole map, or at least prevent the enemy from getting fuel -> this eventually led to the t70 in this game.
This is of course only my opinion, but i think going for 7-8 Osttruppen into flame ht without an munitions cache is more potent. By the time you have 7 Osttruppen you will have the munitions for it anyways, and the enemy has 3 Conscripts on the field.
I uploaded a similar replay -on the same map- earlier today, please watch it and give any insight if you like.
P.S.: Brummbär is such a vanity unit
OK I'll watch it, i bielive that the title of the replay doesnt fully correspond to the content of the game
