They might make him a cop as they did in a few other versions?
Making him a gulf war 2 vet allows him a decent time to rack up the body count.
Gulf War 2, which is still kinda going on, if Sergeant Castle was a headcase before his family was killed, you gotta wonder why he ever came back? Meanwhile if Frank was on leave when his family was killed, that would colour the grieving familyman AWOL and a deserter, which makes him a total black hat in the current climate.
So Punisher can be a GW2 veteran, but it really is a question of how he exited service.
What about a private military contractor like Blackwater?
That way he could have been involved in some soul destroying shit abroad without saying that the US Army is naughty.
In Garth Ennis' Born, the Punisher's origin Story, things got so bad in the shit (Viet Nam), that Frank "prayed" to a higher power to save him from what the hell which was happening in exchange for "nothing clearly defined" which turned out to be taking the war back to the America and continuing the endless slaughter.
Which sounds like what Cytorak asks for in exchange for the power of the Juggernaut.
Although even though Garth seemed to be hinting that the entity was death, I'd always felt like it might be War, which at the time (when I first read it) was a big deal since Ares, the God of War was thugging about on one of the Avengers squads.
Although, if this was Death who was giving Frank the gladeye, then that puts him in a love triangle with the mad titan Thanos.
But essentially, in the right light, he is a "priest" killing to please a god that is empowering him to kill, which is perpetual motion and sort of what Moon Knight is up to half the time.
