A soldier has been formally charged after "losing his rag" during a virtual battlefield exercise and killing his comrades.
The Edinburgh-based Army rifleman is believed to be the first soldier to be punished under UK military law for offences in a virtual scenario rather than in real life.
He is said to have been fed up with being stuck at a computer rather than training outside.
A source from 3rd Battalion, the Rifles told the Mail on Sunday: "We'd spent two weeks sitting in front of laptops pretending we were in a really hostile urban environment - I'd challenge anyone to take it seriously for that long.
"All this was taking place in an office at our headquarters, when we'd rather be doing real-life soldiering outside in the fresh air. But there's less of that sort of exercise these days because the Army has committed to Unit-based Virtual Training.
