You hop into the battered leather thing that you suppose serves as the gunner chair as there are a bunch of controls in front of it. Not bothering to strap yourself in, you take the controls...
The turret emplacement itself resembles dual-linked and twinned Gatling guns. As you bring the system online, they begin to spin as the energy levels rise. Putting the targeting lock on the Tusken Raiders, the gunnery pivots about to face them.
"Urk?" is all one of the snipers manages to grunt before he is shredded by a torrent of blaster bolts.
The rest run for cover behind their banthas. One sniper is daring enough to try shooting at the turret, his bullet pinging off the reinforced viewport that you sit behind.
