Vetting troops for 25 fuel is not feasible. It should only cost manpower.
Honestly, I have a bad losing streak atm too. I almost lost every game of the last 30 I played but there's one thing I have to say about that suggestion:
I don't know if it's a bug but I see often that my troops suddenly die from one second to another when entering a building in mid fight. Let's say 4 Grens enter a building and at the moment when the Unit Icon disappears and they enter the building they die.
I dont know but is it that hard to veto them again?
You guys have problems
When I want to start a game I don't want to check everything that might be changed for no reason.
Next time faction will be reset to Soviet standard.
Maybe after that I have to check my graphic settings every time I launch the game?
