Rant: Game interface design

[Copadope]

This kind of problem was handled quite nicely in Total Annihilation (a similar RTS game of the Starcraft era). TA had a command called "Guard," so you could tell your medic units to guard the fighters and they would follow them around everywhere and fix them whenever needed. This way you could just select the fighters and tell them to attack and the medics stayed back with them. Of course if you're in a pinch and you just start mass selecting and attacking, the system falls apart and the medics start rushing. Guarding also came in handy if you had a large group of various units that needed to travel a long way, because you could tell the quick units to guard the fat, slow ones and they'd all arrive to the fight at the same time.
