Military Services

Can someone tell me specifically the things a country uses military services for each month? I am sure military units use them but what else are they used for? There is a large shortage on KB at the moment and I am looking for a way to reduce my monthly usage until the supply improves.

Bases? Maybe eliminate some.

Possibly but I don't have that many bases and they have their own military base maintenance units. I will take a look. Thanks. Any other ideas?

If you can, build a Mil-Sv. corp. With a shortage, you'll always have them + make a profit.

or anyone who is both on kb and anywhere else can buy it off-world and direct-trade it home to use or sell. no shuttles needed.
