A real American hero is in the Tri-Cities this weekend and he's hoping to share an important message with military families through his new book that was just released this week.
Retired Navy SEAL and Corpsman (medic) Lieutenant Mark L. Donald is the first Navy medical officer to receive a Navy Cross since Vietnam.
The Navy Cross is this country's second highest military decoration for valor.
Donald received the award for his actions in Afghanistan in 2003.
According to the citation, Lt. Donald repeatedly exposed himself to heavy enemy fire while providing medical aid to his comrades wounded in an ambush, then, although wounded himself, he coordinated the evacuation of his fellow soldiers before attending to his own injuries.
Now Lt. Donald is hoping his book, "Battle Ready," will help other veterans heal.
"Yes, I'm a Navy SEAL, I received a Navy Cross, I received a Silver Star, but I have also received some mental scars from the enemy. I have post traumatic stress, I have combat stress, I carry those badges with me everyday of my life," said retired Lt. Donald.
Lt. Donald is signing copies of "Battle Ready," which was just released Tuesday, out at Food City Race Night at BMS Friday night.
He will also be at the Barnes & Noble in Johnson City from 6 p.m. - 8 p.m. Saturday evening.
