The military of the Republic during the Mandalorian Wars and Jedi Civil War was made up of the local militias as well as the sector forces who reported to their generals rather then the central command authority such as the Defense Ministry. They often spent more time as guards on their capital ships than as troopers on the ground.
Republic soldiers wore red and yellow armor and what appeared to be a black bodysuit underneath. Combat suits and Republic mod armor were available to Republic troops as well. Republic soldiers were issued blaster rifles, blaster carbines, blaster pistols, disruptor rifles, and heavy repeating blasters. Vibroswords were used for close-quarters combat due to an increase of close-quarter enemies such as the Sith during the time of the Old Sith Wars. Several types of explosives, such as grenades and mines, were also issued to troops for combat and demolition purposes.
