Yes Commander that's an issue happening to many SI Warriors.

But there is good newsL You will not lose units because credits are negative

Just try to get your credits back to PLUS but be assured when you units are growing in number the negative credits is part of it :)

your "rations" went into the RED, becuase you have reached the point where you NEED to start hammering on "ration consumption reduction", and not "rations production".

first and formost, get your (ATC) up, and to Lv.21 ASAP.

next, go to your (training center), and apply "drill instructors" straight down the middle until you reach "ration consumption reduction", and apply all 80 drill instructors to it. that should get you back to right again.

once you become a "Super Power", you will need to go into the "rations consumption reductions" TAB in the training center, and find the units you are using the MOST of, and get them maxed out.

make sure you max out your (COBRA) resource production buildings, becuase they are the cheepests, and quickest to upgrade. and, once you max them out, they give theyre (perminant) +5 offense, +5 defense, and -2% to ration consumption reduction...

cheers!
