I have heard of one such ex-US marine sniper codenamed Goldfinger who worked for the IRA, he was reportedly on $50k per kill of a British soldier. A SAS team was tasked with tracking him. He didn't return home........
I also know of ex British army soldiers with a trigger finger for hire to the highest bidder..... It stands to reason if you have a skill and someone wants to pay you a lot of money that you will do what you have been trained to do.
Fletch, I'm not saying individuals with the skills don't or can't go out on mecenary ops...it's a fact of life.
This came up when some jerkoff alleged that it was USA policy to have vets on mercenary ops as a way of saying that we are morally equivalent to the scumbag Islamic Terrorist engaged in worldwide terror ops all over the planet.
That is bs enemy propaganda designed to put us on equal footing with monster evil bastards who have the stated objective of annihilating every man,woman and child who is not muslim.
