me when playing i hit fast forward and get as many troops as the point will let me. for the empire i go depending on how many i can 1-2 stormtroopers, 1-2 walkers, 1-2 scouts and the rest maulers if i can. with the rebels 2-3 normal troops, 1-2 plex troops, 1 t2-b or t4-b whatever i have at the time. now i go the whole map before going to the enemies base, and remember to use bombing runs only when you absolutely need them not to be wasteful. if your still having problems try lowering your difficulty level it does help, good luck and welcome to lucas forums
