SF guy writes new book MI VIDA

[hdgb]

Anybody know this guy? Joseph Nathaniel Harris
Got alot of generic SF/ranger stuff up on his FB page website.
Claims service w/ 7thSFGA 12th gp, ranger bn .. I guess this book is about his life and trying to bring attention to undeclared war in Central america. Claims 100% disabled PTSD from service during that time?
I haven't read it. was wondering if this guy is legite as several innocent inquiries have turned up some very concerning anomlies in his story.
I'm in the skeptical camp and i know there are guys on here who will set me straight if this guy turns out to be the real deal.
