Different kinds of "vehicles" capable of rearming ground units.

Now ground units can replenish ammo from trucks, it would be good to have more options like stationary ammo boxes, field warehouses, special ammo carrier vehicles like TZM 9T234. Maybe even helicopter-transportable container that rearms vehicles after being put down somewhere.

Along with this I wonder if the range of ammo supply should be looked at. Right now if you have a widely spaced SAM site, it can be a challenge to fit all the launcher in range of the supply truck. In reality the truck could just drive from one launcher to another as needed. This could be simulated by having a larger radius and a delay time between the reloading of one launcher and the next.
