Infantry used to be cheaper...requiring significantly LESS manpower which made them more viable in the early game. Now, nobody builds them, ever...or at least, rarely ever. They are already fairly cheap, otherwise, though the Food maintenance does add up. I think that used to be a little bit less, also. But then, almost everything has had increased maintenance costs over the years as Bytro's management have tried to "encourage" players to use more Gold.
It seemed like such a waste to destroy an entire battle station just to eliminate one man. But Charlie knew that it was the only way to ensure the absolute and total destruction of Quasi-duck, once and for all.The saying, "beating them into submission until payday", is just golden...pun intended.
