[3] During 1920, the South African Military School was established at what was then called Roberts Heights (This has subsequently changed names twice, first to Voortrekkerhoogte and now to Thaba Tshwane).

The college was granted the status of School in 1924 as a result of the training of the first group of permanent force Officer Candidates.

[3] In November 1953 the Weapon Training Branch was officially renamed the Infantry School in terms of SADF order No.

[3] On 1 January 1964 the new, fully fledged Infantry School opened its portals in Oudtshoorn to admit its first students under the command of Cmdt M. N. Horner, SAIC.

[3] In January 1977 another historic event occurred at the Infantry School that is the advent of the first prospective Cadet Officer intake of then recently qualified teachers.

Later on it had become policy to send companies of National Servicemen to the operational area as part of their training as Junior Leaders.
