Not the Private Ryan from that Tom Hanks war film, but a war veteran famous for his lightning raids on the Powers That Be upstairs.

After a brief stint as an army cook, he could never quite get the food to taste revolting enough and he kept cutting his fingers off, he was transferred to the artillary corps.

He became quite an accomplished soldier and very deadly, but his fear of loud noises meant his constant crying and panic attacks became a nuisance to his fellow soldiers. So again he was "transferred".

Now the junior vice captain of the suicide squad he is responsible for leading raids against "Upstairs" and takes pride in the fact that he is in charge of thousands of bloodthirsty soldiers. So far he has a 100% success rate and has lost over 5000 demons on these raids, though he himself did manage to slightly bruise a small chipmunk and live to tell the tail.

A deadly killing machine indeed, watch out!
