Air Training Corps Chaplain Badge. United Kingdom.

The Air Training Corps (ATC) Chaplaincy is part of the Royal Air Force Air Cadets (RAFAC) and is responsible for providing spiritual support to the ATC community.
Air Training Corps chaplains are usually civilian members of the local clergy (although uniformed forces chaplains may join as Service Instructors).
The role of the chaplain in the ATC is to 'provide appropriate pastoral care for all personnel within the Air Cadet Organisation, irrespective of religious belief or status'.
A chaplain's role in the local squadron is to offer guidance and leadership to cadets and members of staff on moral and spiritual matters.
The commitment expected of a chaplain is a monthly visit to lead what is termed 'the Padre's hour', and to conduct the formal Enrolment Service when new cadets join.
ATC chaplains are supported by the Royal Air Force Chaplains Branch.
ATC chaplains do not wear uniform, but are recognised by a chaplain's badge on their lapel, and a larger version on their tippet (preaching scarf), vestments, or other clerical clothing.
Even if it is not their custom to do so, ATC chaplains are expected to wear a clerical collar ('dog collar') when on an RAF station.
The equivalent No.2 working dress for a chaplain is a dark sweater with chaplain's badge and a clerical collar.
The ATC is organized into regions, wings, sectors, and squadrons. Each region has a Regional Chaplain, and each wing has a chaplain.
