The Army has won its first rugby league inter-services title for five years by beating the Royal Air Force 42-6.
The service had already won their first game of the tournament, beating the Royal Navy 36-16 last week.
Clinching the trophy at the home of professional side Featherstone Rovers in West Yorkshire, the Army started quickly, taking the lead in the first five minutes with a converted Ryan Watkin try.
The second try soon followed through Peter Holmes, giving the service a 10-0 lead, before Dan Tooth increased that lead to 14-0 going into half-time.
In the second half, the RAF started the stronger - Kev Rackaw scoring the try and Si Wray kicking the conversion.
However, after the Air Force got their first points on the board, the Army quickly reestablished their domination.
The fourth Army try was a solo effort - Uraia Naulusala collected Jamie Laing's pass and outpaced the opposition to touch down a converted try to make it 20-6.
Jamie Laing then turned scorer himself, producing two tries of his own, leaving the score 32-6.
With time running out, there was still time to add two further scores, Peter Holmes and Michael Hoyle getting the Army's seventh and eighth tries.
"I was here five years ago, well up in Portsmouth five years ago, when we last got the win," said Army team captain, Staff Sergeant Jordan Kerman.
"It's been too long, it's been far too long, five years."
Warrant Officer Class 1 Ben Taylor, the Army's head coach, said:
"From minute one we just won in every collision."
