Despite their good form at the Stoop last year, team captain Dave Manning is keen not to look past their tough opponents.
He said: "It certainly holds good memories from last year being the first time we won it. We beat both the Army and the Navy teams for the first time in over 25 years too.
"We are under no illusions that they will both be gunning for us this year as reigning champions, but we will be ready for them."
Manning will be joined in the squad by UKAF Sportsman of the Year, Josh McNally. The London Irish player is a key part of the squad and the team have been preparing well for the Navy fixture, according to Forwards Coach Justin Coleman.
He said: "We’ve had some good victories against the British Police and Richmond and some tougher tests that we expected and wanted in the build-up such as the Coventry game and the French Air Force away.
"I think we are in a really good place. We have had those tough tests now and learnt from it. We take positives away from every game to analyse and review.
