Heidi was deployed to Iraq in February 2004, for seven months with a Marine Corps surgical company, when her boy and girl twins were fifteen months old. More on her site.
A clinical psychologist in the US Navy, Kraft's job was to uncover the wounds of war that a surgeon would never see. She put away thoughts of her children back home, acclimated to the sound of incoming rockets, and learned how to listen to the most traumatic stories a war
zone has to offer.
I recently saw her speak very movingly at The Brain at War just held in SF, the focus on veterans of Iraq and Afghanistan. The conference points out:
"Many have served multiple tours - increasing their chances of
post-traumatic stress, traumatic brain injury, depression, and suicidal
thoughts, among other injuries and conditions."
From hearing her, I recommend her book, Rule Number Two.
