When stationed on Hoth, the Rebel Alliance modified T-47 air speeders to become snowspeeders, fast flying conveyances for patrol and defense of their hidden base. It took some doing to keep the crippling cold from permanently grounding their air force, but Rebel ingenuity overcame the relentless Hoth elements. The T-47 air speeder is a small, wedge-shaped craft with two forward-facing laser cannons. In its rear arc is a harpoon gun fitted with a heavy-duty tow cable. The snowspeeder is a two-man vessel, with a pilot and rear-facing tail gunner.
Destroyer Droids, also known as Droidekas, were used by the Trade Federation during the invasion of the planet Naboo. These droids had shield generators and could curl into a ball for rapid movement.
