Sgt. Joseph Love donated his kidney to a fellow reservist, Sgt. Daniel Famous. Famous was diagnosed with polycistic kidney disease 20 years ago, but took a turn for the worse in 2012, requiring a kidney transplant.
Love decided to test whether or not he was a match after Famous, his supervising officer, told him that the kidney disease would keep him from deploying.
"It's part of the army values," Sgt. Love said. "Never leave a fallen comrade... But above the army, I wanted to."
Both men should recover in 4-6 weeks.
"Not only will this enable me to maintain the way of life I'm used to, it will allow me to stay in the Pennsylvania National Guard on my terms until I'm ready to retire," Famous told Army reporters.
