If it was a mercenary commander i’d say it would be a bio-op.
I got a better one - A scoundrel of a soldier that sold military grade weapons to illegal outlets took the opportunity to flee from his post after he was found out by his peers, who then told his commander and was scheduled to be executed. After he drained his offshore bank account with his illegal funds beforehand, he escaped and ultimately died and was resurrected - with his funds still intact.
Only to be killed by a lucky survivor some time later.
