WASHINGTON - The American troops killed in the deadliest single mission of the Afghanistan war came from two dozen states and all corners of the nation, mostly young men in their 20s and 30s.

The Pentagon Thursday released the list of the 30 killed, along with their ages and hometowns in states from Florida to Minnesota, and from Hawaii to Massachusetts.

Family members and friends have spoken to The Associated Press and other media outlets about them.

Here are the stories of some of the fallen:

n A severe arm injury during fighting in Fallujah in 2004 didn't keep Matthew Mason off the Iraq War battlefield. Nor did it dull the competitive fire of the avid runner and former high school athlete from outside Kansas City.

Within five months of losing part of his left arm, absorbing shrapnel and suffering a collapsed lung, Mason competed in a triathlon. He soon returned to his SEAL unit.

"He could have gotten out of combat," said family friend Elizabeth Frogge. "He just insisted on going back."

Mason, the father of two toddler sons, grew up in Holt, Mo., and played football and baseball at Kearney High School. He graduated from Northwest Missouri State University in 1998. His wife, who is expecting their third child - another boy - also attended Northwest Missouri.

n Jason Workman had his sights set on becoming a SEAL as a young teenager. He was about 14 when his older brother graduated from West Point. That's when he knew he wanted to be an elite soldier, friend Tate Bennett told The Deseret News. Then came the Sept. 11 terror attacks, and Workman's calling grew even stronger.

"He didn't become a Navy SEAL by chance," Bennett said. "He knew that's what he wanted at a young age and made it happen."

After returning from his Mormon mission, Bennett said, Workman went to Southern Utah University and later joined the Navy.

Across his small hometown of Blanding in southern Utah, flags were flown at half-staff as residents mourned the loss of one of their own.

n Jon Tumilson got an early start on his preparation to join the SEALS. He had been a wrestler in high school and competed in marathons and triathlons.

Neighbors remembered the Rockford, Iowa, man as a warrior committed to the SEALs, no matter the pain he endured in training or the risks he ran on each mission.

"When he did something, he put his all into it," Jan Stowe, a neighbor of the Tumilsons for more than 30 years, told the Des Moines Register.

Tumilson, who was 35 when he died, "was going to be a Navy SEAL since I can't remember when," Stowe said.

Friend Justin Schriever remembered Tumilson as "a die-hard at everything. He'd always go the extra mile on everything."

n Brian Bill had plans for when he finished his military service. He wanted to return to graduate school and hoped one day to become an astronaut.

For those who knew him, such lofty goals were not out of reach.

"He set his standards high. He was that kind of person," Kimberly Hess, a friend who graduated with him in 2001 from Vermont's Norwich University, told The Advocate newspaper. "He was remarkably gifted and very thoughtful. There wasn't anything he wouldn't do for you no matter the time or day."

Diane Warzoha, who had Bill as a student at Trinity Catholic High School in Stamford, said it was no surprise that he fulfilled his goal of joining the SEALs.

"Brian just wanted to do his best, to protect other people ... Challenge did not deter him, ever."
