The experiment went terribly wrong.

What happened during the seven months Tiger Force descended into the abyss is the stuff of nightmares. Their crimes were uncountable, their madness beyond imagination—so much so that for almost four decades, the story of Tiger Force was covered up under orders that stretched all the way to the White House. Records were scrubbed, documents were destroyed, men were told to say nothing.

But one person didn't follow orders.

The product of years of investigative reporting, interviews around the world, and the discovery of an astonishing array of classified information, Tiger Force is a masterpiece of journalism. Winners of the Pulitzer Prize for their Tiger Force reporting, Michael Sallah and Mitch Weiss have uncovered the last great secret of the Vietnam War.
