WEST DES MOINES, Iowa (AP) — Sgt. 1st Class Nicole Amor was just days away from returning home to her husband and two children when a drone strike at a command center in Kuwait killed her and five other U.S. service members.

“She was almost home,” her husband, Joey Amor, said from their home in White Bear Lake, Minnesota, on Tuesday. “You don’t go to Kuwait thinking something’s going to happen, and for her to be one of the first – it hurts.”

Amor was one of four U.S. soldiers killed in the Iran war on Sunday and identified Tuesday by the Pentagon; two soldiers haven’t yet been publicly identified. The members of the Army Reserve worked in logistics and kept troops supplied with food and equipment.

They died just one day after the U.S. and Israel launched its military campaign against Iran. Iran responded by launching missiles and drones against Israel and several Gulf Arab states that host U.S. armed forces.

Those killed also included Capt. Cody Khork, 35, of Winter Haven, Florida; Sgt. 1st Class Noah Tietjens, 42, of Bellevue, Nebraska; and Sgt. Declan Coady, 20, of West Des Moines, lowa, who was posthumously promoted from specialist. No other names were released.

“These men and women all bravely volunteered to defend our country, and their sacrifice will never be forgotten,” Army Secretary Daniel Driscoll said.

All were assigned to the 103rd Sustainment Command, which provides food, fuel, water and ammunition, transport equipment and supplies.

“Sadly, there will likely be more, before it ends. That’s the way it is,” President Donald Trump said of deaths.

One of the youngest in his class

Coady had just told his father last week that he had been recommended for a promotion from specialist to sergeant, a rank he received posthumously.

He was one of the youngest people in his class but seemed to impress his instructors, his father Andrew Coady said Tuesday.

“He was very good at what he did,” he said.

Coady trained as an information technology specialist with the Army Reserves and was studying cybersecurity at Drake University in Des Moines. He was taking online classes while in Kuwait and wanted to become an officer.

“I still don’t fully think it’s real,” his sister Keira Coady said. “I just remember all of our conversations about what he was going to do when he came back.”

A mother of two who loved gardening

Amor, 39, was an avid gardener who enjoyed making salsa from the peppers and tomatoes in her garden with her son, a senior in high school. She also enjoyed rollerblading and bicycling with her fourth-grade daughter.

A week before the drone attack, Amor was moved off-base to a shipping container-style building that had no defenses, Joey Amor said.

“They were dispersing because they were in fear that the base they were on was going to get attacked and they felt it was safer in smaller groups in separate places,” he said.

He last spoke to her about two hours before she was killed. He said she was working long shifts and they had been messaging about her tripping and falling the night before.

“She just never responded in the morning,” he said.

A calling to serve his country

Khork was very patriotic and drawn from a young age to serving the U.S., his family said in a statement Tuesday.

He enlisted in the Army Reserve and joined Florida Southern College’s ROTC program.

“That commitment helped shape the course of his life and reflected the deep sense of duty that was always at the core of who he was,” said his mother, Donna Burhans, father, James Khork, and stepmother, Stacey Khork, in a statement.

Khork also loved history and had a degree in political science.

His family described him as “the life of the party, known for his infectious spirit, generous heart, and deep care for those who served alongside him and for everyone blessed to know him.”

One of Khork’s friends, Abbas Jaffer, posted on Facebook on Monday that he had lost the best person he had ever known.

“My best friend, best man, and brother gave his life defending our country overseas,” Jaffer said. Khork and Jaffer had been friends for more than 16 years.

A loving father and husband

Tietjens lived with his family in the Washington Terrace mobile home park in the Omaha suburb of Bellevue, Nebraska. He was married with a son, according to a Facebook page.

Tietjens earned a black belt in Philippine Combatives and Taekwondo and was “an instructor who gave his time, discipline, and leadership to others,” the Philippine Martial Arts Alliance said in a Facebook post.

On the mat and as a soldier, “he carried the same values: honor, discipline, service, and commitment to others,” the organization said.

Nebraska Gov. Gov. Pillen paid tribute to the family Tuesday.

“Noah stepped up to serve and defend the American people from foreign enemies around the world — a sacrifice we must never forget,” he wrote.

“We are holding the Tietjens family close in our hearts during this unbelievably difficult time and will keep them in our prayers,” he said.
