Units having the ability to transport other units would be a very useful feature, especially in C&C and similar future maps. I can think of two ways this can work: 1. Units who move onto the same tile as the transport are considered as moving onto the transport itself. If the transport is moved, all the units move with it. In this way the transport is like a movable tile. You could then tab to the units on the transport to control them individually. This is sort of how it works in time of conflict. 2. The units are loaded into the transport, removing them from the map but storing them so that they can be recreated at another point. This way you would summon a unit loaded in the transport back onto the map with the stats it had before being removed. This is how it works in sound rts. Both have upsides and downsides, but I've got a feeling option 2 would be easier to implement but of course I'm not sure. Just some thoughts.
