Sky News reports on a Columbian mercenary in Ukraine and the Revanche Tactical Group, a unit made up of mercenaries from all over the world:
It's thought that Revanche has operated all along the frontlines in Ukraine, and is now directed by Ukraine's military intelligence directorate.
"We invite true adventurers and thrill-seekers to join our ranks - those driven by a hunger to experience life in its sharpest, most intense forms," the group says.
So that's what it's all about - thrills and spills!
Dodging drones and 'experiencing' people being blown to pieces in front of your eyes.
That's the ticket!
Estimates on how many Colombians are fighting in Ukraine vary, but Mario Ivan Uruena Sanchez, an international law professor at Rosario University in the country's capital Bogota, believes the number could be as high as 6,000.
Economic factors are the main driver for Colombians going to Ukraine, Sanchez told the not-for-profit organisation North American Congress on Latin America.
As with all mercenaries the real focus is money, which is to be expected, as all the wars they fight in are usually nothing to do with them, as their country and families are not threatened.
Just like all those Brits who went to fight for ISIS.
