Tonight, the Taliban taking Kabul, Afghanistan's capital and last government stronghold.

Smoke rising over the U.S. Embassy, Chinook helicopters taking off, evacuating U.S. personnel

As armed Taliban fighters swarmed into government buildings and took over the country, the world

was privy to gut-wrenching scenes as thousands of Afghans who served as translators, co-workers

and allies on the battlefield desperately tried, along with their families, to get on airplanes

to leave the country and avoid the inevitable retribution.

Few were more emotionally involved in the effort to save those Afghans than Elliot Ackerman.

A Marine who served five tours in Iraq and Afghanistan earning a bronze star for valor.

frantic efforts, along with others, to line up charter flights to save his one-time Afghan

Reserve, protect and defend.
