Decades after the last grenade exploded and the final rifle was fired, the Vietnam War still rages inside Tony Bresina.
The former U.S. Army infantryman, a longtime resident of Buffalo in Wright County, has battled alcoholism, considered suicide and a decade ago was diagnosed with post-traumatic stress disorder.
He still has visions of friends dying, intrusive images of one soldier being decapitated by helicopter blades and nightmares about the bloody assault on Hamburger Hill, one of the defining moments of the war.
Bresina, 59, is reliving the mortar attacks, the shrapnel showers, the grenade explosions and the snipers' bullets this week as a result of his featured role in a National Geographic TV documentary, "Inside the Vietnam War."
The first showing of the three-hour documentary was Monday. Bresina said he couldn't bear to watch and doubts he will watch encore presentations this weekend.
"I think it's going to be pretty graphic," said Bresina, who retired last month after 32 years as a maintenance worker with the St. Michael-Albertville School District. "I'm going to wait, talk to family and friends, and see what they think."
Barbara Bresina, his wife, said she thought it was important that her husband participate in the documentary.
"The final decision was up to Tony," she said. "I see it as a healing thing for Tony and as kind of a legacy he can leave his kids. It's taking an experience that was life-changing and not positive and turning it into something positive and maybe helping other people."
