"107 General
1. The light armoured regiment consists of a regimental headquarters, a headquarters squadron and three identical light armoured squadrons."
So, all three were light armour, but once THAT particular fad had passed - and with the tanks still mostly laid up - the light armoured regiments converted to recce regiments, sometime in the early seventies. The Strats were orged a bit different, but in Pet the Hussars had:
SHQ
A Sqn in Ferrets
B Sqn in Lynx (Tp Ldrs had APC for the AN/PPS-515, switched to Lynx in 78 or so).
C Sqn was TQ3 Trg Sqn and provided 'Six-Nix' Regtl Recce Tp on Ex.
HQ Sqn
In 78, in response to buying the Leopard C1, the Ferrets were retired, the regiments became 'armoured regiments' , A, B, and C were slated for Cougars (first four delivered to the 8 CH(PL) in Jan 1980), and D Sqn was the Bde Recce Sqn. In late 78 or early 79, D sqn was saved for the fourth Cougar/Tank Sqn in a regt (as that was our doctrine: four tank sqns of 19 tks plus two in RHQ equals 79 tanks, 51 officers 802 men, NOT counting the 7 officers 249 men in the Bde Recce Sqn) , and the Bde Recce Sqn changed from D Sqn 8CH(PL) to Recce Sqn 8CH(PL). And thus it stayed, until we became Recce Regts again, except for the LdSH(RC).
