So look at the board it looks like different planets will build different units.
Ground units are built by the Orange icons. and fleets are built by the blue icons.
Looks like the death star(s) and the SSD are built by the turquoise icon. although I do not see that one on the board.
There is also a secret hidden base space with icons. My guess is that this base must be located at one of the planets that does not have any icons on it. There is at least 1 per sector.
Looks like triangles build the lighter units (fighters and soldiers), then circles, and then squares build the bigger units (ISD and MC80).
Anyone else have any insight?
