After an aborted
mutiny in January 1964, the existing army was disbanded. The new force was titled the 'Tanganyika Military Force', from 25 January 1964 - 26 April 1964. The Tanzanian government concluded that the former British model was not appropriate for the needs of an independent African state. Fresh recruits were sourced from the
Tanganyika African National Union youth wing. After the merge of
Tanganyika and
Zanzibar, the force was renamed the United Republic Military Force on 27 April 1964. However the army was four battalions strong by 1967. From 1964 to 1974, the TPDF was commanded by
Mrisho S.H. Sarakikya, trained at the
Royal Military Academy Sandhurst, who was promoted from lieutenant to brigadier in 1964 and became the force's first commander. He was succeeded by Major General
Abdallah Twalipo in 1974. Twalipo was still a major general in 1975, but then promoted to lieutenant general by 1978 (Kaplan, 1978, 249) and then later full general. In 1972, the
International Institute for Strategic Studies (IISS) listed the army with 10,000 personnel, four infantry battalions, 20
Type 59 main battle tanks, 14
Type 62 light tanks, some
BTR-40 and
BTR-152 armoured personnel carriers, and Soviet
field artillery and Chinese
mortars. 'Spares [were] short and not all equipment was serviceable.'
War broke out between Uganda and Tanzania in October 1978, with several Ugandan attacks across the border culminating in
an invasion of the Kagera Salient. President
Julius Nyerere ordered Tanzania to undertake full
mobilisation for war. In a few weeks, the Tanzanian army was expanded from less than 40,000 troops to over 150,000, including about 40,000
militiamen as well as members of the police, prison services, and the
national service. Fighting in December was mostly limited to "
trench warfare" along the border, marked by sporadic clashes and air raids. By early January 1979 all Ugandan troops had been ejected from Kagera. Nyerere decided that Tanzanian forces should occupy southern Uganda as revenge for the devastation wrought by Ugandan troops in his country and to incite a rebellion against Ugandan dictator
Idi Amin. The Tanzanians launched their offensive in mid-February 1979. Major General
David Musuguri was appointed commander of the TPDF's 20th Division and tasked with overseeing the advance into Uganda. They steadily advanced, killing dozens of Ugandan soldiers and destroying large amounts of their material. Following the capture of
Masaka and
Mbarara, the TPDF halted to reorganise.
Silas Mayunga was promoted to major general and given charge of a newly formed "Task Force", a unit consisting of the 206th Brigade and the Minziro Brigade, which was to operate semi-autonomously from the 20th Division. While the 20th Division moved out of southeast Uganda and attacked major locations in the country, the Task Force advanced north into western Uganda in the following months, engaging Ugandan troops conducting
rearguard defensive actions. The 20th Division captured
Kampala on April 11 and overthrew Amin's government. The fall of Kampala marked the first time in the post-colonial history of the continent that an African state seized the capital of another African country. The war ended on June 3, 1979; after Tanzanian forces occupied Uganda's border region with
Sudan and
Zaire. Some Western military analysts attributed Tanzania's victory to the collapse of the Uganda Army, arguing that the TPDF would have been defeated by most other African armies. Others felt that the TPDF's success indicated substantial improvements in African military capabilities over the previous years. When the TPDF began returning en masse to Tanzania, only a small number of soldiers were demobilised, contrary to public expectations. Military commanders then began making accommodations to render the wartime expansions of the army permanent, creating new units and divisional headquarters. Some in the military hierarchy expressed disapproval in light of Tanzania's bleak financial situation, and the country's depressed economy eventually forced the TPDF to disband many of the extra units. Nevertheless, the TPDF retained a large number of officers in the standing army, with the assumption that they could be used to command militiamen in the event they needed to be called back into service. The post-war size of the TPDF remained larger than the pre-war size throughout the next decade. In 1992, the IISS listed the army with 45,000 personnel (some 20,000 conscripts), 3 division headquarters, 8 infantry brigades, one tank brigade, two field artillery battalions, two
anti-aircraft artillery battalions (6 batteries), two mortar, two anti-tank battalions, one engineer regiment (battalion-sized), and one
surface-to-air missile battalion with
SA-3 and
SA-6 missiles. Equipment included 30 Chinese Type 59 and 32
T-54/55 main battle tanks. In 2007 Tanzania pledged forces for the
SADC Standby Brigade of the
African Standby Force. ==Land Force Command==
