My point was wider just than the one guy. I was dual national once, just British now, as I recall I couldn't fight for my other nationalities army and still be dual national during service. It was a while back and I was contemplating a life in the military.
My point was more the first but of my post. If I had joined the army of the country I am originally from and was killed or captured I wouldn't be a British national killed or captured, just a soldier of the army I was representing no?
Even if I wasn't in the army and was caught by dissidents (there is conflict where I am from) then surely I'm just a local resident?
