Meanwhile, HMS Somerset have just returned back from a match against a Belfast Harlequins XV at Deramore Park.
vThey took a squad of 23 players to Northern Ireland’s capital where they won the fixture, played in four quarters, 22-5.
Luke Jones, fresh from a successful RNRU Under-23 trial, gave Somerset a 3-0 lead in the first quarter with a penalty.
With fly-half SLt George Wheatley pulling the strings, Somerset increased their advantage to 8-0 at half-time thanks to a try by LAET Steffan Phillips while Quins had a man in the sin-bin.
Jones could have given the visitors a larger advantage had he had his kicking boots on.
Quins, who had borrowed Somerset forwards ET (CIS) Chris Swanson and AB (CS) Adam Muller-Bosworth, hit back in the third quarter with a drive try, but the visitors turned on the style in the last 20 minutes, scoring two converted tries.
However, their strong finish came after Phillips had made a try-saving tackle. Phillips then played a major role in Somerset’s second try, which was scored by Wheatly, who converted his own effort.
Their final score came from debutant SLt Benjamin Jones following a line-out move, with Wheatly converting.
