By Mark Duell PUBLISHED: 05:18 EST, 15 January 2014 | UPDATED: 06:21 EST, 15 January 2014 A thug who attacked a soldier from Prince Harry’s air base with a 'cowardly' gang who robbed and beat him unconscious has been jailed for more than three years. Mitchell Ambrose, 20, of Ipswich, Suffolk, took part in the assault on 21-year-old Jack Shilton - who had served in Afghanistan - along with four other gang members who were jailed two months ago. Ambrose was also sentenced for a ‘mindless drunken vandalism’ spree four months before the attack on the Army Air Corps serviceman, who maintains Apache helicopters at RAF Wattisham.
