Hoth Hanger Technicians had an important role to play in the battle of Hoth. The technicians oversaw the shield generator the Rebel Alliance defence against any incoming Imperial attacks. They also helped maintain the Ion cannon used to take out a Star Destroyer and assisted in launching the Rebel Fleet off of the Hoth Planet when the Empire overran the Rebel defences.
A Hoth Rebel Trooper is an infantry unit equipped with special gear who fought for the rebellion on the ice planet Hoth. These units are not specifically trained to work in snow, being regular Rebel troopers equipped with snow gear.
Hoth Trench Troopers featured in Empire Strikes back and could be seen trying to hold off the oncoming attack of Imperial forces whilst the Rebel fleet attempted to evacuate the Ice Planet Hoth.
Rebel troopers (also known as Rebel soldiers and Rebel infantry) were standard foot soldiers employed by the Alliance to Restore the Republic
