Sponsorship
Every yeomanry regiment has a regular regiment to sponsor it and supply it with a series of permanent staff instructors (PSI's). In the case of the North Irish Horse it had been the 1st King's Dragoon Guards from the outset but these ties were broken in 1958 when the KDG amalgamated with the 2nd Dragoon Guards (Queen's Bays) to form the 1st The Queen's Dragoon Guards. From that point onwards sponsorship was given by two of the remaining cavalry regiments of the time which were the 5th Royal Inniskilling Dragoon Guards and the Queen's Royal Irish Hussars both of whom had also had to endure amalgamation in past reforms. Today the Royal Dragoon Guards along with the Queen's Royal Hussars supply the Squadron with PSI's. The Queen's Royal Lancers may also supply PSI's due to being a part of the Queen's Own Yeomanry.
