The pre-Christmas trip to Scotland will be long remembered by the Warriors first team squad as the Royal Marines tested them to the limit, physically and mentally.
Speaking about the trip, Warriors second row forward Lee Mossop told us,
"It was enjoyable but it was horrible at the same time!
"We got a lot out of the Army camp last year and I think we've got even more out of this. The Army camp was just flogging after flogging but with this, we got to do some of the things that they do, which was really good.
"The first night, they kept attacking us and we were on guard, looking through night vision goggles. We had to be alert so we couldn't sleep at all.
"Then on the final day, we did a 10-mile hike carrying logs and machine guns. We got to a frozen lake and we had to break the ice with the logs, wade through it and then carry lads up the banks at the other end, so it was really hard work.
"But it was good team-building work because those kinds of things are twice as hard if you don't talk, and so everyone ends up speaking to one another and getting to know each other well. It really helped us gel as a team."
