SFC Hack,
I read your book over the weekend and enjoyed it.  I found it floating around the VVA office here at Moberly Correctional Center.  Your book give hope about my future.   I feel down a lot and grasp at information to help me along.  I am 43 years old, and Army medic, and did a tour of Iraq 2007 to 2008.  I cam home and began having all kinds of problems.  I was dealing with a hyper vigilance, nightmares, paranoia, and depression.  I got into a fight that turned deadly and came to prison on a manslaughter charge.  I , too, just wanted to go away and disappear when I cam home.  I lost several guys from my FOB, I can’t imagine losing a whole company.   I was a medice for convoy security driving throughout Iraq while dodging IED’s.
I am an associate member in the VVA chapter here.  I do a lot of the secretarial work.  I like it because it keeps me connected to other veterans here at the prison.  I hope to get involved with other veterans organizations when I get out.
Your story give me hope about returning to society and being successful.  I was a firefighter/paramedic and can’t return to my profession because of my felony.  But I will continue to strive to be my best. …

Respectfully,
(Name Withheld)

A message of hope, a message of never giving up.  Time and time again during the three days of the show, Vietnam veterans thanked Sgt. Hack for his book and the understanding, bonding and brother-ship of comrades in arms.
