4th Sector Army
The 4th Sector Army also known as White Cuirass Command, was a Republic and later Imperial Sector Army charged with the defense of Sector 4.
Initially assigned to Sector 4 as part of the Reserve Sector Armies, the 4th Sector Army served as a reserve command for Republic campaigns in the Mid Rim and Outer Rim Territories during the Clone Wars.
Late in the war, it became known as the Outer Rim Sector Army while serving alongside the 13th Sector Army in the Outer Rim Sieges.
It contained Jedi General Ki-Adi-Mundi and clone marshal commander CC-1138's 21st Nova Corps.
After the Declaration of a New Order, a member of House Praji became the Grand Moff of Sector 4 and assumed command of the Sector Army.
