This manga is is backstory of the one whose name I took for my own as a moniker...

DOCTRINE DARK!

I took it shortened as ddark92 (Doctrine Dark 1992 but shortened)

Doctrine Dark from the Street Fighter EX subseries (1997 to 2001) and the Fighting EX Layer series (2018 ownards) is an interesting character, a German soldier who turned psychotic bomb-terrorist because of Guile (of Street Fighter fame) incompetence that lead Ddark's own platoon into a deadly ambush (or so DDark himself believes to be Guile's fault...).
