South Sudan United Front/Army, led by Paul Malong Awan, declared its intention to join the SSOA in April, but this does not seem to have occurred.

Each of the eight member parties would hold the position of chairman for six months, starting with Denay Jock Chagor (having assumed leadership of Gadet's SSUM/A) and followed by Changson of the FDP-SSAF.
