The family of a young soldier murdered at Massereene is asking how another killing outside an army base has been allowed to happen.
Stephen Hughes, whose nephew Mark Quinsey (23) was murdered by dissident republicans at the Co Antrim base, said: "Security needs to be immediately upgraded at all barracks in Britain and Northern Ireland before someone else is killed.
"How many soldiers have to die before the MoD and the Army take action? They seem to have learnt nothing from Massereene in terms of the safety and protection of soldiers."
Mr Hughes said his heart went out to the family of Lee Rigby who was shot dead outside Woolwich barracks on Wednesday: "As a family, we know the nightmare the Rigbys are facing, not just in the weeks and months ahead, but for the rest of their lives.
"Their suffering will have no end. They will torment themselves with questions about what happened. I hope they get more answers from the army and police than we did."
Mark Quinsey and Patrick Azimkar (21) died in a hail of bullets when two dissident republican gunmen opened fire on them as they collected pizza outside Massereene barracks in March 2009.
Stephen Hughes said: "The security at Massereene was abysmal – there was effectively no security at all. Four years later, security for soldiers has again been shown to be just as woeful.
"Young men, who risk their lives for their country, are left totally vulnerable to attack."
Thirty-six hours before the Massereene attack, PSNI Chief Constable Sir Hugh Orde had warned that the threat against police and soldiers was at its highest level in Northern Ireland in a decade.
Despite this warning, Masssereene wasn't put on high alert. The base was protected only by civilian guards with handguns. Mark Quninsey's family questioned why heavily armed soldiers weren't guarding the base or why the squaddies weren't confined to barracks.
Immediately after Massereene, the British Army strongly denied security there was lax but at the recent retrial of Brian Shivers, who was found not guilty of the double murder, the prosecution itself referred to major security lapses.
Mr Hughes said: "A review into security at Army bases finished three months after Mark and Patrick were killed at Massereene. Things should have improved dramatically.
"Yet four years later a soldier can be killed and beheaded in broad daylight outside Woolwich barracks. The national security threat is officially "substantial" yet I see no evidence that heavily armed soldiers are protecting army bases even now.
"The Army and the MoD are seriously failing in their duty of care to soldiers. And it took 14 minutes for armed police to even arrive on the scene at Woolwich which is outrageous."
British Defence Secretary, Philip Hammond, has said the security of British soldiers will be reviewed in the wake of the Woolwich murder. "We take the safety of our troops extremely seriously," he added.
Mr Hughes said: "Actions not words are needed from those in power who claim to care so much about our soldiers."
