This is a list of Royal Air Force Trade Groups .. Each ground trade in the Royal Air Force is assigned to a Trade Group which it operates under for command and control .. Originally , the trades were organized in groups numbering I , II , III , IV & V and M for any medical associated trades .. They were changed into the 22 Trade Groups as shown below in 1951 , and have since undergone amalgamation into 19 groups in 1964 and down to 18 by the early 2000s .. With further amalgamations , only 17 of the original groups now exist .
