Each team has one or more "scout" units which are in communication with the ships in orbit. (Another option is to have officer units be able to call down orbital fire... I'm still considering which to use)
On the space map, scouts are represented by colored markers. The markers move in the same distance and direction as the corresponding scout on the ground map. A scout can only establish radio contact with a ship if his marker is within 6" of that ship.
A scout may call down an orbital strike on any target within 6" of himself if a ship which is able to make an orbital strike is within communication range. The scout can't be inside a building or vehicle with a roof when he does so.
Alternatively, he can call for a reinforcement drop.
Some spacecraft have the ability to jam scouts' radios. If a jammer comes within 10" of a scout marker, that scout is unable to communicate with any orbiting spacecraft.
