"Unfortunately that's not the case now," he said. "A lot of people will have little or no faith. But those who are Catholic and practicing their faith, both military and civilian, that was so huge for them to be able to experience the sacraments.
"Those who take their faith seriously, it is such a blessing for them to see a priest. When you just sit and talk to soldiers, they have such an admiration for the chaplaincy because they know we're there for them."
The Army too has taken notice of Father McDermott and cited both his organizational skills and leadership of the chaplaincy at Bagram and his service on the battlefield as justification for the Bronze Star.
"McDermott has no peer in building a community of worship and spiritual strength. His ministry was vital in establishing a community of faith and spiritual resiliency within the combat theater of Afghanistan," read an evaluation by his superiors who commended him.
"He is a soldier's chaplain who is equally capable in a garrison ministry setting and in the most austere and dangerous locations. His efforts in revamping the Enduring Faith Chapel (at Bagram Air Base), building a community of faith, planning seasonal events, and instilling spiritual resiliency within Service Members and authorized civilians were done flawlessly," it read.
For Father McDermott, the award recognizes not so much as what he is doing, but what God is doing among men and women in the most difficult circumstances.
"I have encountered a lot of people who were away from the Church and the sacraments for years and God has used this opportunity of the deployment to bring them back to church because at any moment there could be an IDF" – indirect fire, or a rocket attack, he explained. "You have no idea when it's coming. So you're living with that, you're facing death every day."
One of the most wrenching duties Father McDermott has performed was helping to carry badly wounded soldiers on stretchers off the giant C-130 transport planes and into the base hospital.
"You see these kids coming in missing arms and legs, burned faces. It affects you," he said. "You're there for them, you listen to them, you talk to them when they can. A lot of them are so angry because of what happened to them, and you're just trying to be Christ to them in that situation."
Not that the priest chaplain is unaccustomed to infirmities himself. Last June after playing in a good-will game of soccer with Afghan soldiers, the 45 year-old Father McDermott tore a ligament in one knee.
Though he needed a brace on the knee while carrying 50 pounds of equipment during his rounds on battlefields, he persevered until returning to the states in early April to Fort Belvoir, an Army hospital in Virginia, for surgery and recuperation.

He is seeing soldiers in the hospital with less serious wounds perhaps than those he'd witnessed on stretchers at Bagram, but he is familiar with the men's interior, psychological damage as well.
"We call it the invisible war that they're about to endure right now," Father McDermott said.
The priest is most impressed with the high level of care wounded service personnel receive. "I wish people would realize how well the government is taking care of these wounded soldiers," he said. "They take tremendous care of (them) here."
Father McDermott does not know if he will be redeployed in the future to Afghanistan. If so, he will again ask the friends and family members who want to send him candy, shampoo or other small items to remember what he really needs as a means of community building and evangelization: a box of cigars that he can pass out to the soldiers.
"I never realized the power of a cigar when it comes to ministry," he said. "When I was on battlefield circulation, whether (the soldiers) were Catholic or not, I would walk into a (headquarters) with a box of cigars like giving out candy, and you just see the guys' eyes light up. They loved that."
Of his decorated tour of duty to his parish community in far-off, war-torn Afghanistan, Father McDermott considers it "a tremendous honor for me personally to serve these brave men and women. And I love them dearly."
