Clone paratrooper/Legends

Clone paratroopers, also known as clone airborne troopers, were specially-trained clone troopers who were trained in high-altitude drops. They wore specialized armor, breathing equipment, and repulsorlift harnesses to help them survive these airdrops. Paratroopers used DC-15 blaster rifles and DC-15 blasters, plus an assortment of thermal detonators and other grenades. The indentation in the front of their helmets helped regulate the airflow as they were dropping into battle. They were also known to act as medics in battle. They might have carried bacta in battles.The clone paratroopers were significant because a gunship did not have to land to get troops on the battlefield. Also, they could ambush and flank the droids from the back.
