For most of its history the Club has provided a comfortable London home for Officers of the Royal Navy, the Royal Marines, the Army and the Royal Air Force. The style and traditions of the Club have tended to follow those of Officers’ Messes.

In recent years, the membership has expanded to include ladies and gentlemen who have not served in the Armed Forces and the Club has benefited greatly from this.

The Club exists as a society of men and women who respect service traditions and who share the facilities of the Clubhouse at No. 4 St. James’s Square for their enjoyment and recreation.

In general a potential Member requires the sponsorship of a Proposer and Seconder, both of whom must be Members. However lack of sponsors does not debar anyone from joining. A potential Member without sponsors will be invited for an interview with a senior Member of the Club before election. That senior Member will then become the new Member’s, de facto, Proposer and Seconder.
