Though the Royal Naval Air Service is usually discussed in terms of aircraft and armoured cars, the list of vehicles deployed also included ambulance cars - indicating an organised ambulance transport function tied to the unit's broader operational mobility.
These ambulances were used to support frontline actions, recover downed personnel, and provide transport for wounded or sick aircrew and support teams behind the lines.
