I haven't really gotten into the German tree that much, was planning on expanding out into more trees as I got burned out grinding teir five was working on the M163 after getting m551 in the american tree. Then got a bit down into the UK and USSR trees, picked up some premiums while they were on sale for teir three. If I recall I brought the AC IV Thunderbolt for the British which is a pretty solid tank and then for USSR the M4A2 AND T-34-57 mod 1943. So far got USSR up around tier three and same with UK. Right now my german pretty much has nothing really, would like to get into that tree, as I really would love to try some of those machines in there. And japan literally has nothing for ground forces. But like I said I kinda stopped playing has much as I use to, due to burnout mainly. and if your wondering air forces, I'm mainly working on the British tree.
