My idea is to make the Command Squad and barracks cost fuel.
When youre starting a game with constripts and engineers the Command Squad is very needed to fight bikes, rush MGs etc.
But what if youre command squad costed fuel (10 or more)?
There would be a possibility to quick cap and tech-up quicker and have quicker strelky+mortars or get the allmighty Command Squad at the beginning.
My second idea is to make a command squad cost more MP and fuel (400MP/40fuel or more) but he would be the retreat point for all units (like UKs captain this retreat would have a recharge time). Infantry would be able to retreat only to command squad positions. There would be no retreat to base.
The command squad could loose its charge ability then so that it wouldnt form a blob quickly and charge anything on its way.
