The
unit insignia was designated in July 1953 - 'Out of water barry wavy
argent/azure a rock proper (grey) thereon a double headed dragon passant Or'
with the motto 'Nihil celerius' - nothing swifter. The rock on
water symbolises the location of the unit - Hong Kong - at the time of the
award in 1953. The double headed dragon is also associated with
the area and is symbolic of watchfulness.
