of 1,000 to 1,500 troops to São Tomé and Príncipe in 1977 to bolster the socialist regime of President Manuel Pinto da Costa. During the next several years, Angolan forces conducted joint exercises with their counterparts and exchanged technical operational visits. The Angolan expeditionary force was reduced to about 500 in early 1985. The Angolan Armed Forces were controversially involved in training the armed forces of fellow Lusophone states Cape Verde and Guinea-Bissau. In the case of the latter, the 2012 Guinea-Bissau coup d'état was cited by the coup leaders as due to Angola's involvement in trying to "reform" the military in connivance with the civilian leadership. A small number of FAA personnel are stationed in the Democratic Republic of the Congo (Kinshasa) and the Republic of the Congo (Brazzaville). A presence during the unrest in Ivory Coast, 2010–2011, were not officially confirmed. However, the Frankfurter Allgemeine Zeitung, citing Jeune Afrique, said that among President Gbagbo's guards were 92 personnel of President Dos Santos's Presidential Guard Unit. Angola is basically interested in the participation of the FAA operations of the African Union and has formed special units for this purpose. In 2021, the Angolan Parliament approved integration of FAA into Southern African Development Community (SADC)'s mission for peace in Cabo Delgado, Mozambique. Angola sent a team of 20 officers to participate.
