OUR commandos are trained to move silently, complete missions with the utmost stealth and then to melt into the background - leaving little trace of their feats behind

April: Cpl Mark Time who served 11-years as a commando is photographed with his successful novel ‘Going Commando’

But as the Royal Marines Corps celebrated its 350th anniversary last month, these former 'Bootnecks' were happy to strip off and put themselves on show in the name of charity.

August: Sgt Rob Driscoll was discharged after being left partially deaf from a grenade attack while on tour - but bounced back to be a successful personal trainer

Now in its fifth year, the Go Commando calendar raises money to help serving and former Royal Marines and their families.  

February: Sgt Tyler Alldis, spent twelve-years as a commando serving in Nicaragua, Honduras, Iraq and Afghanistan

This year's calendar has a brand new focus on the lives of Green Berets once they've left the armed forces and returned to civilian life - under the slogan "Once a Royal Marine, always a Royal Marine". 

December: LCpl Ash Swinford and Cpl Stuart Lee pose for the Christmas season

The calendar tells the story of eleven hunky heroes who have served our country and their lives post-military.

The brave Green Beret’s include Mr May, LCpl Ash Swinard, who was wounded by an IED in Afghanistan in July 2011 – resulting in a below the knee amputation. 

January: on leaving RM Corps, Cpl Lee Stuart started Go Commando Bootcamp

Mr August is Sgt Rob Driscoll, who was discharged after being left partially deaf from a grenade attack while on tour - but bounced back to be a successful personal trainer. 

Mr June WO1 Si Atkinson, a former specialist and world class award winning chef in RM Catering Corps poses with a frying pan, whilst Cpl Stu Beattie, a Falklands Veteran proudly displays his medals from his days in service.

July: Mne Nick Smart flew straight to Sierra Leone on same day as he finished training and served for 12 years

Cpl Mark Time who served 11-years as a commando is Mr April, photographed with his successful novel ‘Going Commando’.

Mark started writing as a therapy to help with the mental health issues he has struggled with since leaving the Marines.

June: WO1 Si Atkinson was a specialist in RM Catering Corps winning a double gold in the Culinary World Cup

Mark, now an author and journalist, said: “Family is really important to me and it’s important in the Marines.

“The ethos behind the charity is the family bond, the brotherhood in the Corps and the wives, girlfriends mothers and children.

“You come out of the Royal Marines and you go into civvy street but a lot of the skills you have, normal jobs don’t really need and it can be quite a lonely place.

March: Cpl Arnie Thacker toured in Malta, Aiden, Malaya and Singapore

“The calendar itself goes right up from boys who have just come out of Afghanistan to those who are getting towards their mature years.

MAY: LCpl Ash Swinard was wounded by an IED in Afghanistan in July 2011 – resulting in a below the knee amputation

“The wide spread of the calendar encompasses the idea that even when you’ve left the Royal Marines you’re still involved – you are part of a brotherhood.”

November: Cpl Stu Beattie Main is a Falklands Veteran who served 26 years and is now a vehicle mechanic in civvy street

The calendar was shot by former Royal Marine, Martin Hill, who hung up his boots to turn pro-photographer.

He shot the images at civilian locations relevant to the military charity and the former Marines featured.

October: Act Sgt Pete Howe was discharged from the Marines when he broke his leg in a freak accident and now runs his own gym

Keeping it in-house the commando collaboration was designed and printed by Andy Screen, and Jason Chappell - who stars as Mr September in the calendar. 

Go Commando was founded in 2010 by businessman Sean O’Brien and is run by chief executive, Debbie Howarth.

September: Men Jason Chappell served as a Royal Marine for six years and now runs a design agency

The 2013 Go Commando calendar alone raised a staggering £120,000 for the cause.
