I would guess a key difference is that these soldier according to this article deserted the Irish military. Militaries tend to frown upon people leaving on their own schedule.
A bit off topic. This made me think of an American Hero who was so anxious to fight the Nazis that he deserted his unit (I believe Army) and went off to Europe.
this guy was a ferocious and fearless fighter.
When the US got into the War her returned to the Army and was court marshaled. His commanders were so impressed with him and felt bad about doing it. I am certain he won the Medal of Honor in WW II.
He served in the Korean conflict and again was absolutely ferocious against the enemy. He won more medals.
He even went on to serve in Vietnam. I believe he was called "big red" or something because of his red hair.
It was fascinating to read about this warrior.
