He anticipates there will be scenarios that his schooling at Penn State University and the Philadelphia College of Osteopathic Medicine, or any other higher place of learning, couldn't prepare him for.
Nevertheless, he said, he welcomes the challenge and will draw on his experiences in the emergency room at University Medical Center, his field work as an emergency technician in Pennsylvania's Pocono Mountains and the lessons he learned in the aftermath of the Sept. 11, 2001, terrorist attacks. Two days later, he was sent to ground zero in New York from Washington, D.C., to provide medical support to federal agency responders.
Heck, who commands the Reserve's 6252nd Army Hospital in San Diego, could have accepted the commander's deferment and declined a three-month tour in Iraq.
"But my number came up," he said.
As a volunteer citizen-soldier in the Army Reserve, he felt obligated to follow through after he was allowed to delay deployment in February last year while the Legislature was in session and before he assumed command of the 6252nd.
"I had given my word I would go on the next rotation," he said. "I'm going on 17 years in the Reserve. This is what you train for.
"Nobody wants to go to a combat zone, but there are dedicated men and women who put their lives on the line every day to protect our freedoms," he said.
Much of his motivation to serve stems from the sight he saw while driving through New Jersey toward New York City with paramedic Jason Kepp to provide support at ground zero after the attacks. The drive took them through an area where they had grown up.
"It was the most heart-wrenching experience I ever had," Heck said. "We looked across the river, and the towers weren't there. There was a huge plume of smoke and dust. We both fell silent and couldn't speak."
Heck's flight today is destined for Atlanta. From there he'll go to Fort Benning, Ga., where he'll be issued his equipment and a handgun. Then he'll go through a week of training before heading to Kuwait and "then to wherever we'll be assigned."
"My goal and my motivation is we've seen 44 casualties from Nevada in both Afghanistan and Iraq, and I want to make sure there's no 45," he said.
Back in Henderson, wife Lisa, whom he described as "the most understanding wife in the country," will be waiting for him along with Joey, 10, Chelsea, 20, and Monica, 21.
Lisa said she realized "a long time ago when I met him" that there would be times when his obligations with the Army Reserve would send him away for months at a time.
"It wasn't a shock to me," she said. "But this one is a little different because of where he's going."
His mother, Mary Heck, and father Joe Heck Sr. said they, too, are concerned.
"Like all moms, I'm worried," Mary Heck said. "I've got to be positive."
