Hi-drop troopers

Orbital shock troopers, colloquially known as hi-drop troopers or simply drop troopers, were a class of clone troopers in the Grand Army of the Republic that specialized in orbital entry via specialized pods that typically carried a squad of drop troopers (or other aerial infantry units). They rivaled airborne troopers and played a similar role to High Orbit Precision Entry (H.O.P.E) commandos, though they were distinct specialties in different departments of the Grand Army.

Equipment
Most orbital shock troopers wore armor very similar in design to standard phase II clone trooper armor, though with extra accommodations such as a chest-mounted life support box and a modified helmet, allowing drop troopers to operate in and withstand pressure at higher altitudes. Some drop troopers wore armor similar in design to airborne troopers. Whereas airborne and H.O.P.E troopers were regarded as special forces, drop troopers were often trained to the same capacity as standard clone troopers, and was often equipped with standard issue weapons such as the DC-15S and DC-15A. H.O.P.E troopers, among other commando classes, also typically had their own naval detachment for transport, whereas drop troopers and airborne troopers, like most of the Grand Army, relied on the Republic Navy for transportation between deployments and air support.

Some drop pods would land directly on the surface with assistance from small repulsorlifts, while others open at a certain altitude, after which point the drop troopers would jump out of the pod and descend to the surface either using jetpacks, repulsorpacks, or specialized parachutes.
