The Royal Navy finished their Inter-Services Rugby League campaign a win in a closely fought match against the RAF at Portsmouth.
The RAF's Sam Breeze opened the scoring after eight minutes but the Navy hit back through Sean Houghton.
Nathan Barker replied for the RAF but a brace of tries from Josh Coupland put the Navy ahead to finish 12-10 at half time.
After the break, Jamie Birdsall picked up on a loose ball to extend the Navy's lead.
Ben Mellor retaliated for the RAF but with the score tied at 16 all, a period of frustration ensued with two massive hits on Navy players which resulted in Juite Tupua being penalised for a particularly strong challenge.
