BS Reason to you..
Having a handgun gets you two years in prison must suck to fight for a country that will put you in jail for that kind of thing. I know he broke the law and has to do the time but it still sucks that he put his life on the line for his country and gets 2 years for IMO a B.S reason.
To the country he served, that Passed those laws, not so much..
Also as I said, it looks like he was tried by the military, so there may be far more reaching reasons.. Like stealing the gun from the army he serves for example ? Not following the UK equipment of the Uniform Code.. There may be more than he simply had a gun at his house, that lead to the 2 years..
