no it doesn't. AchtAchter made that perfectly clear.
Sure, the moment you have to pay for the Lieutenant, Captain, Major.
Also cheaper teching is relative
Costs for the first P4 280 Fuel
Costs for the first Sherman 265 Fuel (270 if you buy the mandatory ambulance)
Costs for the first Stuart 115 Fuel
Costs for the first Luchs 120 Fuel
It's practically mirrored.
