Two FDNY members were among the seven soldiers killed in a military helicopter crash in Iraq — including a father of two who was on his last tour of duty, heartbroken family and friends said Friday.

Fire Marshal Christopher “Tripp” Zanetis and Lt. Christopher Raguso died Thursday when their Pave Hawk chopper struck a power line and went down along the Syrian border, authorities said.

“He loved what he was doing. He loved rescuing people,” grief-stricken dad John Zanetis told The Post. “That’s one main reason he was a New York City fireman, and the reason he joined the [Air National] Guard.”

Zanetis, Raguso, and five others with the 101st Rescue Squadron were headed to provide support on a nighttime mission when they went down near al-Qaim, Iraq, according to Zanetis’ mother, Sarah.

“They were probably flying pretty low to avoid being picked up by radar. Somehow the rotors got hit by power lines,” the dad told The Post.

“That’s the danger of flying at night. Instruments don’t pick up the power lines.”

Zanetis, 37, never shied away from danger, his parents and officials said.

A 10-year veteran of the FDNY who was cited for his bravery in 2014, Zanetis was serving his third tour of duty abroad.

He was on his second deployment in Iraq, and had also completed a stint in Afghanistan.

The latter was highlighted by a death-defying rescue attempt that left Zanetis in need of a rescue of his own — which came at the hands of a British Army detachment led by Prince Harry.

“[Zanetis] suddenly got caught in the crossfire” while hoisting a victim on a stretcher onto the chopper, Zanetis’s father recalled.

“A surveillance plane told him to get out of there,” the elder Zanetis said. “He radioed back that he couldn’t, he had people on the ground.”

“Prince Harry came in with his protection squadron and blew the enemy to pieces,” Zanetis said, adding that his starstruck son snuck a picture with the royal at a New Year’s party.

“Everyone loved him,” the father recalled, choking back tears. “He was tough, but he was very lovable.”

Raguso was similarly mourned by colleagues outside a firehouse in Commack, LI, where he lived and also served as a volunteer fire lieutenant.

Raguso, a 13-year FDNY vet with six department citations for bravery, told a January going-away party that this would be his last tour of duty abroad, said Commack Fire Commissioner Pat Fazio.

“He was ready for it to be the last one. All he wanted to do was come home in May,” Fazio said.

Raguso, who turned 39 just three days ago, would have come home to his wife, Carmella, and two daughters, ages 5 and 6.

“I said I think that’s awesome to devote your time to family and kids,” Fazio said outside the firehouse, which was draped Friday afternoon in ceremonial bunting.

“I have a job to do, and that job is to look after Carmella, his wife, his parents, his in-laws, and most importantly those two little girls. Daddy’s not coming home,” Fazio said.

Raguso’s family declined to speak with reporters Friday.

Raguso, who worked out of FDNY Division 13 in Queens, was on leave to serve overseas.

Zanetis, whose parents said he was single and lived in Manhattan, was also on leave as he pursued a career as a lawyer.

Raguso and Zanetis are the 1,148th and 1,149th members of the FDNY to die in the line of duty, Commissioner Daniel Nigro said in a press release.

There are currently 62 members of the department on military duty around the globe.
