WCS cadets now
A cadet detachment was re-formed at the school in 2007 and we are called 234 Detachment KRRC (King’s Royal Rifle Corps). We are part of NW London sector ACF. The KRRC is a direct descendant of the QWR and cadets are allowed to continue to wear the KRRC cap badge (even though the regiment is disbanded) as some KRRC cadets won a battle honour during the South Africa war in 1901 and are the only cadets ever to do so. Only 3 other cadet detachments have this honour as well as being able to call our cadets Riflemen instead of ‘cadets’
The cadets wear a collar sized KRRC style cross in black on green berets.
