The US air squadron involved in the friendly-fire incident in Iraq that killed Lance Corporal Matty Hull has apologised to his family.
A spokesman for the Idaho National Guard said it was "very sorry that this incident happened".
"We're obviously very, very sorry to the family and extend our sympathies to them," Lieutenant Tony Vincelli said.
Prime Minister Tony Blair earlier said he "deeply regretted" the distress caused to L/Cpl Hull's family by the delay to the inquest into his death.
The US pilots involved in the "friendly fire" attack that killed L/Cpl Hull near Basra in March 2003 were reservists from the Idaho National Guard's 190th Fighter Squadron who had never been in action before.
Both are now training junior airmen in diving and strafing in A-10 warplanes.
The case has prompted accusations of the MoD conspiring with the Americans in a cover-up of the circumstances of the death of the soldier from Windsor, Berkshire.
A US cockpit video and recording of the American pilots involved had been withheld from the inquest, but was leaked to The Sun newspaper, prompting the Americans to agree that it could be shown to the coroner.
A transcript of the footage reveals that the pilots, a major and a lieutenant colonel, say on several occasions they can see orange panels on top of the armoured vehicles beneath them, which were used to identify them as coalition, rather than Iraqi, forces.
But they convinced themselves that the orange panels were enemy rocket launchers and opened fire.
