I have no idea if it is sensible or not, but could an extra base building possibly be contructed as an "espionage" base for the russian urban or propaganda doctrines?
By this I mean a building that only constructs:
snipers-with the current requirements
spies-single man squads that are able to camoflage and booby trap points but have virtually no health and cost a bit less than snipers.
Recon units-even lighter, unarmed, vehicles than the kattenkrad that can only be used to enhance the players view or mark targets (much like the shwimmwagens luftwaffe ability)
Intellegence commander-A non camoflaged unit that can call in local militia, much like the soviets conscripts only a reinforcement type unit. Also, the mere presence of the commander near the espionage troops cuts down their recharge on the abilities that they may posess (In much the same way as the PE's munitions halftrack).
It's just a suggestion and i am aware that the developers do not really have time to explore these endeavors. I was merely wondering if the idea of a doctrinal base building is feasable or not.
