A Chaplain serving with HM Forces is addressed by his ecclesiastical rank, and never in speech by his relative Service rank, which is only for administrative purposes.
It is not necessary or usual to write the Service rank, but when used formally it must appear in brackets after the ecclesiastical title and before the Chaplain's Christian name or initials. For example, The Reverend (Air Vice Marshall) A B Bloggs Royal Air Force.
The Heads of Chaplaincy for each of the Services can be chaplains from any of the contributing Churches, so there is no title common to them (see below).
