Navy second row colleagues Marsh Cormack and Damo Chambers will go head to head when they meet each other this weekend with their respective civilian clubs. On Saturday Marsh will be representing Taunton whilst Damo will be in Launceston's colours. It is not the first time that the two have gone head to head as they have met before at Command level where they are part of the fierce rivallry that has grown between the Fleet Air Arm and the Royal Marines. Last season it was Damo who came out top as the Corps side defeated Air Command to lift the Inverdale Cup. The two power houses are more used to working together and will again be in harmony when they join forces as the Navy looks to retain the Commonwealth Cup, to be played in Plymouth during early October. They will be renewing a partnership that has proved very successful for the Navy but was unfortunately not seen at last season's Inter Services due to Damo breaking a bone in his foot. The pair will come together when the Navy play a warm up game against Watsonians in Edinburgh on 8th September and again at Redruth when the Navy take on Cornwall on 23 September. The two will no doubt be the senior lock pairing at Brickfields when the Navy take on the South African Navy (6th October KO1900), NEw Zealand Navy (9th October KO1900) and Australian Navy (12 October 1900).
