The chaplain general is a senior chaplain in non-church organisations, such as the British and Canadian armies, and are responsible for conducting religious services and ceremonies, representing the Christian faith in that organisation.
During the First World War, the chaplain-general John Taylor Smith was equivalent to a major general and under the control of the Permanent Under-Secretary of State. Llewellyn Henry Gwynne was from July 1915 deputy chaplain-general of the army in France, with the relative rank of major-general. Both had been colonial bishops prior to appointment.
In the Second World War, the head of chaplaincy in the British Army was an (Anglican) chaplain-general, who was formally under the control of the Permanent Under-Secretary of State. An Assistant Chaplain-General was a Chaplain 1st class (full Colonel) and a senior Chaplain was a Chaplain 2nd class (Lieutenant Colonel).
In 1948 the first Bishop to the Forces was appointed; the Bishop is a suffragan of the Archbishop of Canterbury, the full title of the Bishop to the Forces is "The Archbishop of Canterbury's Episcopal Representative to the Armed Forces". The Bishop to the Forces is not a military chaplain. The current holder of the office is the Right Reverend . There is sometimes confusion between the (Anglican) "Bishop to the Forces" and the (Roman Catholic) "Bishop of the Forces": for this reason the latter is normally given his title in full, i.e. "The Roman Catholic Bishop of the Forces".
Each of the three armed services has a chief chaplain (ranking as an archdeacon), for the navy the Chaplain of the Fleet, for the army the Chaplain-General, and for the Royal Air Force the Chaplain-in-Chief.
