Station Warrant Officer
The Station Warrant Officer (SWO, often pronounced as a word) is the senior Warrant Officer on a British Royal Air Force station. The SWO is responsible for discipline and is therefore comparable to the Garrison Sergeant Major in a British Army unit. He is the station commander's link to the other ranks and his eyes and ears on the ground for all issues that may effect the smooth running of the station.
Once a member of the Royal Air Force has reached the rank of Warrant Officer or Master Aircrew, they are eligible to apply to be a SWO. There are a few cases of Flight Sergeants acting in the position of SWO.
