I think Captain Colossus likes to 'split hairs'. Its fair to say that SB can be played in a RTS style if thats what you enjoy. Indeed, in larger scenarios with many units to control, you spend more time looking at the map and giving orders from there, moving your attention around the battlefield to where its needed. Also, i think the GUI in SB is far superior to that of the Graviteam titles.
The AI are "competent" in crew drills, but require the right orders/tactics for the situation.
Check out some gameplay videos (link is a few posts up) to get a look at different ways it can be played.
