So how did 22nd Dragoons end up as the senior regiment in 30 Armd Bde?
This all came about due to Lancer and Dragoon loyalties of the Brigade Commanders.
Brig. Peto, 29 Armd Bde, was a Lancer whereas Brig. Anstice, 30 Armd Bde was a Dragoon. So a little shuffling around was agreed and 22D were swapped with 24L(24th Lancers). This was only possible because both Brigades were still forming up.
This is described in more detail in the footnote on p12 of Raymond Birt's XXII Dragoons 1760-1945: The Story of a Regiment.
