Keep Your GMP in the Black
You use GMP for acquiring gear, upgrades, calling in requests, and sending things back to base. You also need to fund the operations on Mother Base. Fuel, materials, and food are all needed by your army, and none of it comes free. If your GMP starts to drop, that means you can’t supply as much stuff as you were before. If it hits the red, then you’re in serious trouble.
Morale will start to drop among your soldiers as they feel they aren’t getting proper care and compensation. This will lead them to becoming serious jerks (like they were before you kidnapped them), and when things get really bad, they will begin to defect from the Diamond Dogs.
Always make sure to keep your funds up. If you’re having a bit of trouble doing so, consult this handy guide to keep Boss and co. rolling in credits.
