These musclemen are all Royal Marine commandos, the elite amphibious fighting force of our Royal Navy. The highly trained and toned fighting machines took a break from their action-packed schedules to strip off for the 2014 Go Commando charity calendar. The stylish black-and-white shots include pictures of Royal Marine commandos on HMS Kent and physical training instructors (PTIs) at the Commando Training Centre in Devon. The pictures were taken by Photographer Emily Nolan, who has previously won the Commandant General Royal Marines photography prize, the Peregrine Trophy.
