4 South African Infantry Battalion was transformed from a Motorised Infantry Battalion to a Mechanised Infantry Battalion in the early 1980s. The name 62 Mechanised Battalion Group was used to indicate when the unit was grouped with the other elements allocated to the battalion for conventional warfare, but was never formally approved as the unit name. This grouping only took place when the unit deployed for operational purposes as a mechanised force.
