The Rebel mortar trooper, also known as the thermal detonator trooper or grenade trooper, was one of the classes of ground units which was deployed during the Galactic Civil War by the Alliance to Restore the Republic. Strategically positioned behind front-lines, mortar troopers played a key role in combat by providing medium-ranged supporting fire for other Rebellion ground troops, launching mortars and thermal detonators. They served with Princess Leia Organa when her transport crash landed on Krant. They fought alongside Leia and Luke Skywalker on Eredenn.
