About: Operation Moduler

Operation Moduler (sometimes incorrectly called "Modular") was a military operation by the South African Defence Force (SADF) during the South African Border War. It formed part of what has come to be called the Battle of Cuito Cuanavale. The Angolan objective was to advance south-east to attack the UNITA (National Union for the Total Independence of Angola) at Mavinga. The SADF objective was to protect UNITA by stopping that advance. The advance was halted with heavy Angolan casualties. The South African forces and its UNITA allies then began offensive operations against the Angolan forces, who had retreated back to a defensive line east of the Cuito River with the objective of destroying them once and for all.
