Geonosian Soldier Drones do a variety of jobs, but are mostly shown guarding the droid foundry and getting sliced and pounded in Attack of the Clones. This is my basic Geonosian design (a Battle Droid with martian legs- I'm stuck with tan until we get brown Battle Droid pieces or LEGO makes their own) with grey flippers attached to a tan 2x2 L plate which then attaches to the stud on the back of it's torso to act as its wings. He also uses a sonic blaster, as can be seen in the second picture.
