By 1987 the U.S. Defense Intelligence Agency estimated the army was 40,000 strong (with Ethiopian army strength estimated at the same time as 260,000). The President, Mohamed Siad Barre, held the rank of Major General and acted as Minister of Defence. There were three vice-ministers of national defence. From the SNA headquarters in Mogadishu four sectors were directed: 26th Sector at Hargeisa, 54th Sector at Garowe, 21st Sector at Dusa Mareb, and 60th Sector at Baidoa. Thirteen divisions, averaging 3,300 strong, were divided between the four sectors – four in the northernmost and three in each of the other sectors. The sectors were under the command of brigadiers (three) and a colonel (one). Mohammed Said Hersi Morgan has been reported as 26th Sector commander from 1986 to 1988. Barre's son, Maslah Mohammed Siad Barre was commanding the 77th Sector in Mogadishu in November 1987, and later became Chief of Staff (also reported as Commander-in-Chief) of the Army. FCO files at Kew indicate that Maslah may have become Commander-in-Chief in early March 1989.
