The field squadrons are 171 strong making them larger than an infantry company in the British Army but, critically, due to the nature of their structure, a key limitation is that they are only able to operate up to Company/Squadron level and so cannot bring the same 'Mass' to bear of an Infantry Regiment or Battlegroup. Not all personnel on an RAF Regiment squadron are trained gunners but can be involved in specialist support services such as administrators and drivers. A typical RAF Regiment squadron has support elements from the RAF but these personnel do not always deploy on patrols and other combat operations. Formerly, all RAF Regiment personnel were men, as it was British government policy that women could not serve in close combat units. However, the intention was that by the end of 2018, women would be allowed to apply for these roles, with the RAF recruitment website 'looking forward' to female applications for the RAF Regiment. A review in 2017 determined that, although the Regiment was deemed to be the Royal Air Force's infantry, it was more alike to the Royal Armoured Corps in terms of risk. As a result, women will be allowed into the RAF Regiment from September 2017, which is a full year before other infantry units. In January 2020, the first female recruit to complete the 20-week training course, passed out of RAF Honington.
