Hi, I'm sure this has probably been posted on here before, so sorry if it has. I'm hoping to join the Royal Marines in 2 years when I turn 19. I know the course is very demanding so I was wondering if anyone has any tips on how to build myself up for it. Could anyone also give me any info on the Mountain Leader specialisation, how long I'd have to be in for before I could do it, and is it quite a tough course? Any help would be useful cheers, Alex.
