I'm like that too... For Force Commander in the Imperial levels I preferred going in strong rather than pissing with little forces. The unit cap screwed that sometimes, but I tended to focus on a less heavily fortified command center in terms of fixed items, and instead used mobile weaponry...
That would leave me hefty stacks of walkers broken into multiple armored columns I could rove the field with and bring hell to the Rebels wherever they were. Opening multiple fronts and stuff. The only fixed emplacements I insisted on having were the necessities like a landing platform w/TIE Fighters to act as scouts. The Fighters practically defended the base themselves and mauled infantry and other aircraft... They were just great to scout up to a point, the fringe of a dangerous area, then you marched your now massive armored column up and beat the piss out of whatever was there...
I love the actual military aspect of these games... The control you have. With that broadened for EAW, I'm even that much more bummed I can't get into it right now.
