63 Mechanised Battalion Group was a unit of the South African Infantry Corps; although it was classed as mechanized infantry, it was a combined arms force consisting of infantry, armour and artillery. Together with 61 Mechanised Battalion Group and 62 Mechanised Battalion Group, these units made up 60 Brigade encompassing battlegroup principles.

63 Mechanised Battalion Group was part of 60 Brigade, based at Lohatla Army Battle School[1] and was formed in 1988 mainly from the operational battalion of 8 South African Infantry Battalion and Ratel 90 Squadrons from 1 Special Service Battalion. Support companies of anti-tank, storm troopers (sapper), 81 mm mortars and their logistical team were also transferred from 1 South African Infantry Battalion in October 1988 to 8 South African Infantry Battalion for integration during a brigade level exercise at Lohatla Army Battle School called Exercise Sweepslag prior to the Group being sent north to South West Africa. The initial commander was "Blok " Liebenberg, a veteran of 61 Mech.

Sector 10 South West AfricaEdit

63 Mech was seconded to the command of Sector 10 in northern South West Africa in 1989 for its short operational life of about 12 months.

A combined Brigade level exercise with 61 Mech and 62 Mech occurred in the Oshivello area in January 1989.

Operation MerlynEdit

63 Mech [1] took part in one strategic operation, repulsing a major incursion of SWAPO into Namibia, in April 1989:

  • On Saturday 1 April, reports were received of Koevoet, a unit of the South West African Police SWAPOL, taking losses from multiple contacts with SWAPO insurgents.
  • On Sunday 2 April, 63 Mech now with Koevoet, engaged SWAPO insurgents near Oshikango. 1 Casspir was hit with AK and RPG fire.
  • On Monday 3 April, tracking of the insurgents began. Allouette gunship helicopters assisted in visuals. Some 32 SWAPO were killed or captured.
  • From Tuesday 4 April, tracking continued around Oshikango.
  • On Wednesday 5 April, the unit divided into 3 search groups.
  • By Thursday 6 April, the area around Onamagula was being searched, when a column drove into an ambush. A Ratel was lost. About 16 SWAPO were killed in the ensuing battle.[2][3][4]
