The ISC Pacification Army comprised nearly 5,000 ships at the onset of the ISC War of Pacification, organized in nine numbered fleets. In the aftermath of the ISC War of Pacification, the Pacification Army was gradually disbanded and the ships put on mothball.
In the 24th century, some high ranking (but retired) military leaders decided that action had to be taken to pacify the small wars and conflicts that were slowly destroying the civilisations in the galaxy. These retired commanders, who still had considerable military power staged a coup and took over the government council on ISC Prime with assistance from loyal members of the Interstellar Concordium Pacification Army, sparking the 2380 Interstellar Concordium Pacification War.
