I also suggest you to do the following experiment.
Play a generated battle in 2010 in a not very dense terrain.
1.Set one side to Germany the other side to Russia.
2.Buy troops for both sides for equal points.
3.Buy infantry only to the opponet(AI).
4.Buy infantry mainly to your force BUT also buy some cheap(without TI) APCs for yourself as well, Fuchs with 30mm if you are the Germans or some BTR with equal punch if you are with the Russians. Let's say cca 2-3 APCs per infantry company.
5. When you play keep the APCs well behind the range of the infantry AT platforms (except ATGMS but you will find ATGMs expensive relative to these cheap pieces of metal). Spray every exposed infantry with your mobile MG nests in form of APCs. You will see the difference

.
"Oh but then I could buy stronger armor to oppose the APCs" - you may say. And the the story continues as you see

.
Good gaming,
