Go outside it is easy to hit the AAT tanks in the bank panel as they exit the hanger, and it is almost impossible to get shot by people, as it is in hoth.
Go to the center platform where the main battle is (it is the one with the round barrier/cover structure on it) go just behind the top of the ramp where the Republic troopers come up. it is easy to snipe them coming up the ramp, it is easier than Kashyyyk because the either stop or keep coming straight up, so there is virtually no aiming involved.
