and Zimbabwe formed a joint security committee 13. The aim of the committee was to monitor operations on a day-to-day basis and to attempt to remove all security threats along the Tete Corridor. Zimbabwe's First Mechanised Battalion was ordered to move into Mozambique and they established their headquarters in Tete thereby securing the strategic bridge crossing the Zambezi River. In 1985, President Samora Machel of Mozambique formally requested the governments of Tanzania and Zimbabwe to contribute troops for "the restoration of law and order" in Mozambique. This led to the deployment of Tanzanian troops north of the Zambezi river and Zimbabwean troops to the south. The decision to send Zimbabwean troops to help restore law and order in Mozambique was partly influenced by Zimbabwe's close relationship with the Mozambican government which dates back to FRELIMO's assistance during Zimbabwe's war of liberation. There was also the underlying fact that FRELIMO and ZANU shared a common Marxist ideology of scientific socialism. The South Africa-backed RENAMO professed to be an anti-communist movement, as did Jonas Savimbi's UNITA movement, which was fighting against the Marxist MPLA government of Angola. There was thus an ideological alliance of the Maputo – Harare – Luanda axis, with support for these governments from the Soviet Union. The fact that the United States of America was providing covert and overt support to opposition movements such as UNITA in Angola and RENAMO in Mozambique reflected the extension of the Cold War to Southern Africa. Angola (United Nations Angola Verification Missions) There were three United Nations Missions to Angola under UNAVEM. UNAVEM I (January 1989 to June 1991) and UNAVEM II (May/June 1991 to February 1995) involved small numbers of unarmed military observers. Brigadier Michael Nyambuya of Zimbabwe was Chief Military Observer of UNAVEM II between December 1992 and July 1993. During UNAVEM III a Zimbabwean battalion was deployed to eastern Angola, based in the town of Saurimo. Nine Zimbabwean peacekeepers died during the UNAVEM deployments. Angolan Civil War After several hints, some of which the Zimbabwean Government denied, for the first time the ZDF Commander, General Constantine Chiwenga, acknowledged ZNA involvement in the Angolan Civil War. It was reported that Zimbabwe had more than 2,000 combat troops, including 20 military intelligence officers, deployed in Angola whose presence has helped the Angolan Armed Forces to overrun Jonas Savimbi's strongholds, according to reports reaching the Zimbabwe Independent.
