"Reflecting on what your faith brings to you, your background, and having that underpin who you are is very important to any person," he said. "And for me personally, it really helps in the command role that I have now."
Cavoli is also visiting Lourdes for the first time. Unlike Harrigian, he was very familiar with the story of Lourdes and had been wanting to visit.
"I've been hearing about [Lourdes] my whole life, since I was a kid, so this is a unique opportunity to get to do something I've wanted to do so much," he said.
Cavoli told CNA that he finds his faith to be "intertwined" with his military career, and calls upon his faith to provide the graces needed to carry out the duties of his job.
"Of course, I have my strictly military duties, which are mainly secular in nature, but the moral compass that religion gives me, the moral compass and the ethical fortitude, as well as the emotional strength to deal with what is a pretty hard profession, that helps me a great deal," he said.
Additionally, Cavoli credits his faith with giving him the wisdom to make the choices in tough decisions, as well as "the strength to carry on when things are hard."
One of the benefits of the International Military Pilgrimage is that it gives servicemembers a chance to be surrounded by people who have similar experiences and can understand and empathize.
"It gives folks time to be together and to share their thoughts. In this case, in the context of their faith, which adds strength to the discussion."
Of course, soldiers, sailors, and airmen train and deploy to defend lives and to risk their own in the service of others. But an inherent truth of military service is that it can involve armed conflict and the taking of human life.
Even in pursuit of the noblest cause or in defense against the clearest of evil, killing and death leave marks on the consciences of all those involved. The "moral injuries" of armed conflict can be as real and as in need of healing as physical wounds.
"Moral injury is a serious thing," Cavoli said, offering that civilians could best help in the healing process by not make assumptions about the experiences of servicemen and women. Listening comes before understanding, he said.

During the pilgrimage, there were major events for all pilgrims, and smaller events for subsets. Both Cavoli and Harrigian said that they considered a shared Mass for English-speaking pilgrims, including servicemen and chaplains from the U.S., the U.K., and Ireland at the Lourdes Grotto, to be a highlight of the journey.
"The Mass at the Grotto was absolutely moving. It was beautiful," said Cavoli. Afterwards, he joined a group for the Stations of the Cross, something he said added up to a "beautiful, beautiful morning" that was "just perfect."
Harrigian called the Mass was "a great chance to just reflect upon everything that this experience brings to the entire community of warriors that are here, along with our families."
And while neither had visited the baths when they spoke to CNA, both were carrying specific intentions with them.
"Personally, internal to our family, I'm always looking for grace and the opportunity to appropriately look over all those that I work with and work for, in the role that I currently have," Harrigian told CNA. He said he was extremely grateful to the Knights of Columbus for orchestrating Warriors to Lourdes, which he called "an incredible event."
Cavoli had similar intentions, saying he would be praying for "Peace, my soldiers, [and] my family." He has appreciated his time in Lourdes, saying it was a place that made him feel "very calm" and fully aware of the presence of God.
