Unusually, B Squadron is the senior of the regiment's five squadrons. This is because the Royal Wiltshire Yeomanry is the senior Yeomanry regiment in the Yeomanry Order of Precedence, having been raised in 1794. It is not designated as A Squadron (which would be the usual practice) because there was already a Royal Wiltshire Yeomanry squadron in the Royal Yeomanry with which it could be confused. In summer 2014, this Royal Wiltshire Yeomanry Squadron joined the Royal Wessex Yeomanry, becoming Y Squadron.
