The championship win was boosted by their performance in the first game, a victory against the Navy, and Roberts complimented his players for moving on from an unsettled warm up to the tournament.
“We’ve had a few games,” he said.
“We’ve not had great preparation if I’m being honest and you know, I spoke about earlier that we have been struggling this year with front row in terms of availability and not having massive front row players in terms within the army at the minute.
"We had an 18-year-old and a 19-year-old that started today.
“For me, it’s really really promising moving forward. We thought it would be an area of weakness but in actual fact, it turned into one of our areas of strength. Those two young lads have come in and added real value.”
For Roberts, it’s not just the players that are learning but his coaching staff too.
He explained: “It’s almost a breeding ground for coaches as well. The young up and coming coaches like myself taking over as head coach and stuff is really pleasing because everyone has got all sorts of energy and enthusiasm.
“It’s about channelling it in the right direction and that is the trick with age group stuff. You need to challenge that enthusiasm and eagerness to do stuff and try to get together a piece of a gameplan.
Roberts also revealed that the Inter Services win has come as a shock. He said: “It’s really pleasing. If we said at the beginning of the year that we would be the Inter Service Champions, I would have probably said no.
“At the end, as we’ve been building and going through, we kind of knew in the squad that we had it within ourselves. It’s pleasing that we have come out and delivered.”
