This post is subject to funding approval. The Air Security Force (ASF) mission is to secure and protect the Air and Space missions, capabilities and people through the delivery of counter threats, police and protective security effects.

Key Responsibilities: Support the OC in the command, leadership, and management of the Sqn HQ team and RAF Police reserve personnel at RAF Waddington and RAF Leeming, ensuring a cohesive, flexible, and professional Force Element (FE) of the ASF. Provide oversight and support for the delivery of all 3605 Sqn outputs, including readiness, training and assurance, administration, and engagement. Support training and provide assurance and RAF Police SME guidance to RAF Police reserve personnel at RAF Cosford (605 Sqn) under a Memorandum of Understanding. Support the OC in fostering an environment that attracts, supports, and develops PTVRs in the RAF Police Reserves, offering meaningful opportunities for mobilisation and Reserve Service Days. Assist in maintaining effective relationships with key stakeholders, including the Reserves Directorate, 2 Group Reserves, HQ ASF, Reserve Forces and Cadets Associations, Reserve Support Wings, and parent stations/establishments.
