The Circuit of Service Lodges, formed in 1993 and currently comprises 26 lodges, exists to promote comradeship and fraternal contact between military masons. The Lodges and the Arm or Service affiliation are listed on the site. To qualify as a member of the circuit a lodge must have a distinguishable military culture and ethos that can only be achieved by a predominance of servicemen or veterans in its membership ranks. Additionally, the Circuit now seeks to encourage individual membership from Masons who have similar backgrounds and interests but who perhaps do not belong to a qualifying lodge.
