A grenadier was a type of soldier specifically trained to use grenades in combat. In the conflict known as the Galactic Civil War, the Alliance to Restore the Republic had at least two grenadiers in its ranks. One was Yosh Calfor, a partially deaf soldier who became a member of the Rogue One squad that went to Scarif with the mission to steal the Death Star plans. The other was [Maximian Ajax](/article/maximian_ajax], a rebel trooper who served within the Alliance's 61st Mobile Infantry.
The grenadier character was initially introduced to the public in the 2015 mobile game titled Star Wars Rebels: Recon Missions.
