The aftermath of the 2003 Iraq invasion is told by former New Zealand SAS soldier Barrie Rice in his book We Were Blackwater - Life, death and madness in the killing fields of Iraq.
Here he recalls lucrative private security contracts, on what soldiers call "the circuit"; the ambush of the Blackwater security convoy in Fallujah, and living with PTSD.
Rice has worked as a military advisor on films including The Hurt Locker, and Zero Dark 30.
