A Royal Navy officer who was murdered trying to stop a gun rampage on board a nuclear-powered submarine will receive one of the highest medals for bravery posthumously today.
Lieutenant Commander Ian Molyneux's widow Gillian will be given the George Medal by the Queen at an investiture ceremony in Buckingham Palace.
Lt Cdr Molyneux, 36, was awarded the accolade - second only to the George Cross - for attempting to tackle Able Seaman Ryan Donovan as he ran amok on HMS Astute while it was docked in Southampton on April 8 last year.
The father-of-four from Standish, Wigan, tried to disarm Donovan after hearing shots on board the submarine on April 8 last year, but was shot in the head.
Donovan was jailed for at least 25 years in September 2011 for murdering Lt Cdr Molyneux and attempting to murder Lieutenant Commander Christopher Hodge, Petty Officer Christopher Brown, and Chief Petty Officer David McCoy.
Major Justin Stenhouse of 1st The Queen's Dragoon Guards will receive the Distinguished Service Order (DSO) at the ceremony for single-handedly taking on Taliban insurgents to save the men under his command.
The officer, from Hartfield in Sussex, was serving with an elite reconnaissance unit when he and his men found themselves pinned down in an attack as they attempted to recover weapons being used against them.
He ran forward into open ground to throw himself into the line of fire and put the Taliban fighters on the back foot.
The DSO is the second-highest military honour for active service.
