Debi Allbutt has spent ten years trying to hold the MoD to account over the death of her husband, in March 2003.
Corporal Stephen Allbutt died in a “friendly fire” incident in Basra.
Debi felt there could have been better training for the use of equipment.
She said: "In every day life our employers have a duty of care to all their employees, so what makes the MoD any different?"
