Colonel Charles Barnett, from the Services Prosecuting Authority, said outside the court:
Sergeant Danny Nightingale has said that he is still struggling with a brain injury he received during an endurance marathon in 2009.
He said "there are now things in my head that are not facts" and added that he sometimes had difficulty recognising his own family members.
His wife Sally added: "He never brought a weapon into the country ... He still confabulates and still struggles with his brain injury on a day-to-day basis".
Much of Sgt Danny Nightingale's court martial rested on conflicting accounts of how the gun and ammunition came to be in a home he was staying in.
- The prosecution accuse him of changing his story. He allegedly told police that the gun had been a "trophy" given to him in Iraq and that he had accumulated the ammunition from training sessions in the UK. Nightingale later told the court martial that someone else had put them there.
- The defence allege that Sgt Nightingale's memory was affected by a brain injury and that his confession to police was false because he was "confabulating" (filling in gaps in his memory based on what other people had told him). He said he had "no recollection of receiving the gun".
Asked whether he planned to fight on for his proclaimed innocence, Sergeant Nightingale said he had to ask the question: "Realistically can we keep going?".
He said that he had concerns about the "longevity of the family".
The solicitor for Sgt Danny Nightingale has tweeted that the family will be seeking advice on whether to appeal against his conviction by a court martial board for illegally possessing a pistol and ammunition:
Speaking outside the court martial, Sergeant Danny Nightingale has apologised to taxpayers for footing his ongoing legal battles.
He said that his own part in covering legal bills had been "financially debilitating".

During the course of the court martial, Prosecutor Timothy Cray accused Sergeant Nightingale of making a "series of mistakes" and of changing his story:

Judge Advocate General Jeff Blackett said he would release Sergeant Nightingale on bail while a decision was made.
Sergeant Nightingale was previously sentenced to 18 months' military detention at an earlier trial. This was reduced to 12 months' imprisonment, suspended for a year, on appeal.
