Brian Shivers, who has been acquitted of murdering two British soldiers, had denied all involvement in the gun attack outside the Massereene Army barracks in Antrim.
Sappers Mark Quinsey, 23, and Patrick Azimkar, 21, died in the attack and two other soldiers and two pizza delivery men were seriously injured in the shooting in March 2009.
The soldiers, who were just hours away from deploying to Afghanistan, were shot dead by two masked gunmen as they collected pizzas outside the gates of the barracks.
Judge Mr Justice Donnell Deeny delivered his reserved judgment after the non-jury retrial at Belfast Crown Court.
