In February 1924 the War Office authorised the establishment of an Infantry Unit and the right to wear the Gordon Tartan. The Infantry Unit was commanded initially by Major J Boyd Orr, DSO MC; later John Boyd Orr, 1st Baron Boyd-Orr. The Pipe Band was instituted in 1924 and became one of the most popular features of the unit. In 1929 the Scots Guards provided the Senior Warrant Officer of the Permanent Staff and established a Household Division link. In 1935 it was decided that the cap badge, which up to then had been the University Crest, should be replaced by the Boar's Head, the family crest of the Founder of the University with the motto "Non Confundar," translated: 'I shall not be troubled.'
