A secretive ‘underground railroad’ of former and active-duty veterans is attempting to rescue Afghan commandos and others trapped outside NATO-held Hamid Karzai International Airport – and plans to continue their operation after President Biden’s Navy withdrawal. “Now we’re thinking about how we’ll get them overseas in an innovative way without using the airstrip. That’s a little more difficult, but we’ll get it done” retired Army Lt. Colonel Scott Mann said on Friday. A group of veterans and volunteers from mostly outside of Afghanistan utilize an encrypted chat to help people get through security breaches.
