Cowbridge rugby coach Richard Killock has paid tribute to Captain Thomas Clarke.
Richard Killock coached the serviceman as a junior describing him 'as a very good rugby player, totally tough and committed but off the pitch he was as gentle as they come.'
Captain Clarke, 30, from Cowbridge, enlisted as an army officer in May 2007, undertaking officer training at the Royal Military Academy Sandhurst. He then joined the Army Air Corps as a pilot.
