Collins was a professional soldier who had qualified as a Ranger and had seven Army Achievement Medals and three Army Commendation Medals to show for his 12 years in the Army. When he was sent to Iraq in September, family members hoped his experience would help keep him safe.
"I figured his odds of surviving were way better than the average person that hadn't had the training he had," his father said.
Following announcement of his death, former classmates at Magnolia High School in Texas organized a memorial service. An acquaintance, Michelle Brady, described Collins as "this skinny little high school guy playing football and having a good time."
He married his high school sweetheart, Kassie, and she survives, as do two daughters, Taylor and Landry.
Sgt. Collins was buried at Arlington National Cemetery.
