"Over the last eight to nine years there has been a dynamic change in the age of fighters. Most fighters now are between 14 and 18 years-old," said Lieutenant Colonel Guy Jones, commander of 2-508th Parachute Regiment, 82nd Airborne Division, based in Arghandab.

"In 2002, fighters were 22 to 30-years-old and commanders were between 32 and 40," said Jones who is on his fourth tour in Afghanistan.
