Former Royal Marines commando Sam Laird

As his friends went off to university, Sam was writing a will and heading to Afghanistan. On four tours of duty he lost many close friends, but the toughest thing for Sam - like so many others - was leaving the military behind.

Sam has turned his experiences into a positive and now coaches and mentors a wide-range of people, using his incredibly determined mindset to help others benefit from the dark and the light that comes from what he has been through.

With thanks to everyone at REORG - a charity that uses martial arts and other activities to help veterans and others improve their mental and physical health.
