[Updated Friday at 7:53 a.m. ET] The U.S. Defense Department released the names of U.S. military personnel killed in Saturday's downing of a helicopter in Afghanistan.

Thirty-eight people were killed in that attack, eight of them Afghan military personnel. It was the single largest loss of life for U.S. troops since the Afghan war began in late 2001.

Of the 30 Americans, 17 were Navy SEALs.  Twenty-two of the dead were U.S. Navy personnel, the Pentagon said.  Fifteen were SEALs belonging to the top-secret unit that conducted the raid that killed al Qaeda leader Osama bin Laden at a compound in Pakistan.  Two others were SEALs assigned to a regular naval special operations unit.

Five were so-called conventional forces with particular specialties who regularly worked with the SEALs. The other eight U.S. troops killed were three Air Force forward air controllers and five Army helicopter crew members.

NATO said it killed the militants responsible for the attack.  Taliban spokesman Zabiullah Mujahid rejected that, saying a NATO airstrike killed a separate group of insurgents.

The following list was provided by the Defense Department:

The following sailors assigned to an East Coast-based Naval Special Warfare unit were killed:

Lt. Cmdr. (SEAL) Jonas B. Kelsall, 32, of Shreveport, La.

The Shreveport native was in charge of Saturday’s mission in Wardak province near Kabul. His father, John Kelsall, who heads Lakewood, California’s, Chamber of Commerce, told CNN affiliate KTLA in a statement, “The country will never understand the level of service those guys gave us.” KABC reported that Kelsall, 33, was trained in San Diego, and he met his wife of three years while attending the University of Texas.

Just weeks ago, according to CNN affiliate WTKR, Houston gave an American flag - which he’d worn under his armor during his last three Afghanistan tours – to veteran Chris Kelly, a man who inspired him. Kelly told the station he was too heartbroken to be interviewed.

John Ball, one of Mason’s former teachers and football coaches, told KSHB-TV that someone approached him asking if he remembered Mason, who graduated in 1992 before moving on to Northwest Missouri State University, where he played baseball. Ball said he immediately remembered his former student and his occupation. “I looked at him and said ‘Don’t tell me, don’t tell me, don’t tell me,’ ” Ball told KSHB-TV. Mason lived in Virginia Beach, Virginia, with his two sons and his wife, who is expecting a third child in November, KSHB-TV reported.

Special Warfare Operator Chief Petty Officer (SEAL) Stephen M. Mills, 35, of Fort Worth, Texas

Special Warfare Operator Petty Officer 1st Class (SEAL) Darrik C. Benson, 28, of Angwin, Calif.

He was born and raised in Angwin, a small town in Napa County, California, so it was natural that people wanted to know about his SEAL training.

The soldiers killed were:

Chief Warrant Officer David R. Carter, 47, of Centennial, Colo.  He was assigned to the 2nd Battalion, 135th Aviation Regiment (General Support Aviation Battalion), Aurora, Colo.

The National Guardsman had dreamed of being a pilot since his high school days in Kansas, CNN affiliate KDVR reported. He was a chief warrant officer at Buckley Air Force Base in Aurora, Colo. “He was flying our nation’s elite forces into combat and, as an aviator, for him that is what he wanted to do,” Col. Chris Petty, a fellow pilot and Carter’s friend, told KDVR.

Carter’s family friend Yolanda Levesque spoke at a news conference in Centennial, Colorado, on a hilltop selected because its view of the surrounding hills was one of Carter’s favorites, according to KDVR. “He was an outstanding husband and father, son, brother and soldier,” Levesque said. “He was a friend to all who met him ... quick with a smile and always with a twinkle in his beautiful blue eyes.”

Chief Warrant Officer Bryan J. Nichols, 31, of Hays, Kan.  He was assigned to the 7th Battalion, 158th Aviation Regiment (General Support Aviation Battalion), New Century, Kan.

Bryan Nichols always wanted to be a solider. His father was in the Army and fought in Vietnam, his ex-wife Jessica Nichols said. Bryan and Jessica met in sixth grade, and she said he enlisted in the military before they had graduated high school. Nichols worked his way up through the ranks, and eventually piloted a helicopter with which he’d had a boyhood fascination. “He came across the Chinook …” she recalled. “His father flew Chinooks.” During the years Bryan and Jessica were married, he did three deployments. She had their son, Braydon, who is now 10. Bryan and Jessica’s marriage ended amicably, and he remarried.

Together with Bryan’s new wife, the three helped raised Braydon. The little boy dreamed also of flying one day, alongside his father, Jessica Nichols said. The boy, instead, posted an iReport on Saturday about his fallen father, in the hopes that the world would never forget him.

Patrick Hamburger had a 2-year-old daughter with Candie Reagan, whom he was planning to marry when he returned to Nebraska next May, his brother said.  He was also helping raise Reagan's 13-year-old daughter. Hamburger sent an e-mail to Reagan the day before his death.

"Please don't worry about me," Hamburger wrote.  He added, "this place isn't going to change me, I'm going to change this place."

Sgt. Alexander J. Bennett, 24, of Tacoma, Wash.  He was assigned to the 7th Battalion, 158th Aviation Regiment (General Support Aviation Battalion), New Century, Kan.

“You wouldn't find a better flight engineer or soldier. … Wherever Alex goes, I will go so I can pay my final respects,” Kuykendall said. Bennett loved cars and the military, and pal Edward Tuck fondly recalled in a KOMO interview the time they spent under the hood of a Honda talking about life.

Spc. Spencer C. Duncan, 21, of Olathe, Kan.  He was assigned to the 7th Battalion, 158th Aviation Regiment (General Support Aviation Battalion), New Century, Kan.

Duncan left his hometown in Kansas because he wanted to serve his country, The Olathe News reported.

"He wrote how much he loved his job as a door gunner on a Chinook helicopter," the local paper said. "But he also told his friends that in the quiet amid the stark landscape of Afghanistan, he missed the Kansas sunsets, lying in a truck bed listening to the radio and cuddling with his sweetie."

The airmen, who were assigned to the 24th Special Tactics Squadron, Pope Field, N.C. that were killed were:

Tech. Sgt. John W. Brown, 33, of Tallahassee, Fla.

The technical sergeant from Siloam Springs, Arkansas, studied pre-med before joining the U.S. Air Force to become a pararescueman, his mother, Elizabeth Newlun told CNN affiliate KFSM. His friend, Jon Woods, told the station that Brown was popular, athletic and loved a challenge. “He was just an all-American G.I. Joe, just a great guy who loved his country,” Woods said.

Newlun read KFSM a letter that Brown’s uncle had written, describing the airman as “Rambo without the attitude” and “brave but never arrogant, powerful but always gentle.” He was married and had no children.

Staff Sgt. Andrew W. Harvell, 26, of Long Beach, Calif.

The combat controller with the 24th Special Tactics Squadron was not only a "bad-ass warrior" but also, a loving husband to wife Krista and caring father to sons Hunter and Ethan, his wife said in a statement.

"We will miss him forever but we take solace knowing he gave his life serving his country and fighting for what he believed was right."

Harvell was stationed at Pope Air Force Base, which this year was merged with Fort Bragg, before heading to Afghanistan, according to the Air Force.

Tech. Sgt. Daniel L. Zerbe, 28, of York, Pa.

The 28-year-old Air Force medic joined the military right after graduating from high school in 2001, according to CNN affiliate WGAL-TV. A native of Red Lion, Pennsylvania, who wrestled and played football, Zerbe was a team player who could always be counted on, his former football coach told the station. His friend, Mike Vogel, who joined the Marines after high school, called Zerbe an “absolute hero,” and Red Lion schools superintendent released a statement, saying, “Dan wanted to make a difference in the world, so he joined the military,” according to CNN affiliate WHTM.
