I typically just avoid the right side of this map, because that's where all the tanks hang out and shoot each other. Mobility is not an issue on this map, because there are plenty of tanks and speederbikes (but having one nearby when you need it is another matter). It can also lead to ridiculous situations where you're winning 30 to 1, but a lone enemy on a speederbike is continually capturing command posts and moving on to another, stalling your win. Scouts are the unit of choice to deal with those tall turret gunners. Use either heavy troopers or Boba Fett as tankbusters, and try not to get too upset with your AI troops for refusing to defend what they cap.
