Corporals Danny Foster, 30, and Philip Beer, 34, both face charges of ill-treatment of a subordinate at the trial at Portsmouth Naval Base.
The court has heard members of 5 Troop 43 Commando would hold a daily gathering called Family Time in the television room during which forfeits would be handed out for minor misdemeanours.
The alleged incidents took place while the troop was tasked with guarding Faslane Naval Base, home of the fleet’s nuclear submarines on the River Clyde in Scotland, and at the Royal Naval Armaments Depot at nearby Coulport, where the nuclear weapons are stored.
Marine Ryan Dunn, one of two alleged victims, told the court the two defendants would “lead” the punishments handed out.
He said the punishments would be either chosen by the throw of a dice or by playing a version of Deal Or No Deal using a PowerPoint presentation projected on to the wall, with one of the marines playing Noel Edmonds, including wearing a fake beard.
He said that on one occasion he had completed the Deal Or No Deal game and had come out with one of the more lenient punishments when Cpl Beer, acting as The Banker, stepped in and gave him the New Born Baby, punishment which involved shaving off all body hair.
Mne Dunn said he shaved all his body apart from his backside and added: “I didn’t want to take a razor blade to that part of my body.”
He said that the following morning Cpl Beer asked another marine to inspect him and then ordered him to shave again but he refused.
He said that the two defendants then ordered him to run repeatedly up and down a hill for about one-and-a-half hours while carrying scaffolding poles and other heavy items from a building site.
The trial has heard other punishments given out at Family Time included one based on the Quentin Tarantino movie Django Unchained, involving a marine being hung upside down naked and whipped, and another involving a marine committing a sex act while watching gay porn.
Foster denies three charges of ill-treatment of a subordinate and Beer denies two counts. The trial continues.
