A Cuban armoured brigade with T-62s saw action against the Somalians during the Ogaden War in Ethiopia. Cuban T-62s were deployed to Angola during Havana's lengthy intervention in that country. Along with T-55s and T-54Bs, they were initially utilitised for defending strategic installations, such as Matala, the site of an important Angolan hydroelectric plant manned by Soviet engineers. The more ubiquitous T-55 was favoured for combat duty, and during the Battle of Cuito Cuanavale only a single battalion of Cuban T-62s took part in the fighting. This was altered in March 1988, when Cuba began marshalling a combined arms division to carry out a flanking manoeuvre towards the South-West African (Namibian) border. It included a brigade with at least 40 T-62s, identified alternatively as 40 Tank Brigade, 80 Tank Brigade, or the "Havana Tank Regiment". The Cuban tanks clashed with defending South African armoured units at Cuamato and again at Calueque without sustaining serious losses.
