Despite its shortcomings, the SSDF played a key role in fighting between Somalia and Ethiopia in the summer of 1982. After a SNA force infiltrated the Ogaden, joined with the WSLF and attacked an Ethiopian army unit outside Shilabo, about 150 kilometers northwest of Beledweyne, Ethiopia retaliated by launching an operation against Somalia. On June 30, 1982, Ethiopian army units, together with SSDF guerrillas, struck at several points along Ethiopia's southern border with Somalia. They crushed the SNA unit in Balumbale and then occupied that village. In August 1982, the Ethiopian/SSDF force took the village of Goldogob, about 50 kiloeters northwest of Galcaio. After the United States provided emergency military assistance to Somalia, the Ethiopian attacks ceased. However, the Ethiopian/SSDF units remained in Balumbale and Goldogob, which Addis Ababa maintained were part of Ethiopia that had been liberated by the Ethiopian army. The SSDF disputed the Ethiopian claim, causing a power struggle that eventually resulted in the destruction of the SSDF's leadership.
