I help cadets and recruits learn how to get the perfect mirror shine without it flaking as soon as you put them on your feet, or spending days building up a base to work from.
I spent 12 years in the Royal Air Force Regiment, 2 on the Queen's Colour Squadron (now the King's Colour Squadron), the only unit in the British Armed Forces to spend 9 months on parade and 3 in the field, even the guards do less drill than QCS!!!
