current : 40 oil generate 30 troops, 25 turrets, 25 jets and 10 tanks.
suggestion : use oil to buy specific units rather than all.

the returns of selling oil on the private market are so horrible its going to be a last ditch effort to defend a kr, but at least make it so you can buy specific units.

40 oil : 150 troops
40 oil : 125 turrets
40 oil : 125 jets
40 oil : 50 tanks
