(NewsNation) – President Joe Biden will attend a dignified transfer on Friday at Dover Air Force Base to honor the three US soldiers who were killed in one night attack earlier this week.

The return of fallen troops to the United States after an honorable death is one of the most solemn moments a president can experience. It occurs whenever an American military member dies while serving overseas.

Minister of Defense Lloyd Austin will join Biden for the transfer in Dover. They happen when US soldiers are killed in action. It is still unknown how The US military will respond to attack.

The attack was carried out by one Iranian-backed militant group According to the US, three soldiers were killed and dozens more injured at a base in Jordan on Sunday.

The service members killed Sunday were all from Georgia and served in the Army Reserves: Sergeant. William Jerome Rivers from Carrollton, Sergeant. Kennedy Sanders from Waycross and Sergeant. Breonna Moffett from Savannah. Sanders and Moffett were posthumously promoted to sergeant.

The deaths were the first U.S. casualties blamed on Iran-backed militia groups that have stepped up attacks on American forces in the region since the war between Israel and Hamas began in October. Separately, two Navy SEALs died during a January mission aboard an unflagged ship that was illegally transporting Iranian-made weapons to Yemen.

“These service members embodied the best of our nation: unwavering in their bravery. Unwavering in their duty. Unyielding in their commitment to our country – they risk their own safety for the safety of their fellow Americans and our allies and partners with whom we work in the fight against terrorism,” Biden said earlier this week. “It’s a fight we won’t give up.”

At the National Prayer Breakfast at the Capitol on Thursday, Biden recognized Rivers, Moffett and Sanders by name and vowed again to never forget their sacrifice for the nation.

Moffett turned 23 just nine days before her death. She joined the Army Reserve in 2019 but also worked for a home care service, cooking, cleaning and running errands for people with disabilities.

Sanders, 24, worked in a pharmacy and coached children’s soccer and basketball while training to be an X-ray technician. She volunteered for the mission because, according to her parents, she wanted to see different parts of the world.

Rivers, who was 46 and went by the name Jerome, joined the Army Reserve in New Jersey in 2011 and completed a nine-month deployment to Iraq in 2018.

Her death highlighted the dangers facing the U.S. military in the Middle East.

Since mid-October, the Pentagon has reported more than 160 attacks on U.S. forces in both Iraq and Syria.

Following the Drone attack on SundayBreonna Moffett’s mother described the heartache of losing her daughter.

“It just takes your soul and your heart. They can’t do anything and know that we weren’t there to protect her or talk to her or change places with her. We weren’t there for them,” Francine Moffett said.

The President spoke to the families of the fallen service members and expressed his condolences.

All families supported the president, who attended Friday’s ceremony.

Biden will not speak during the dignified rendition, a sad ritual that has become increasingly unusual in recent years as the U.S. has withdrawn from conflicts abroad, particularly the war in Afghanistan, where the U.S. was involved for two decades.
