The former Delta Force operator who made it his life's work to track, identify, and hunt down human traffickers. Jeff Tiegs spent more than 25 years in Army special operations, from Ranger private to Green Beret to Delta Force operator and troop commander, with combat in Panama, Iraq, and Afghanistan and a Silver Star for valor in Iraq. After The Unit, he pointed the same hunt at a different enemy. Through Guardian Group and then Skull Games, the nonprofit he founded, veterans and analysts scrape ads, slang, emojis, and open-source networks to find women and children being sold and the people selling them. The work runs on volunteer hunts and a Survivor-Hunter track that trains women who got out of the trade to work the intel beside the veterans. Early reporting on Skull Games credited the effort with freed victims, recovered missing children, and dozens of predator arrests, in both cities and small towns. Tiegs has said he fought al-Qaeda, ISIS, and the Taliban, and that the people preying on girls are a worse enemy.
