Actually, most of the vehicles are designed to run on a wide variety of fuels. I think most of the tanks can even be converted to wood-burning mode if need be.

Food, water, and humans can be acquired from the local populace. Unless you're invading a death world, I guess.

Replacement parts and artillery shells are still a concern, but lascannons and lasrifles will keep a regiment going for a long time.
