October 7, 2011, marks the 10th anniversary of the U.S.-led war in Afghanistan, a conflict that has drawn passionate praise and criticism since its beginning.
The war began in response to the 9/11 attacks in 2001, with the goal of ending al Qaeda terrorist activity.
To look back on 10 years of war, CNN asked service members, contractors and Afghans how the conflict changed their lives. We gathered 10 of those that outline 10 very different experiences in the years of war, but the contributors all have one thing in common: Their lives will never be the same.

America's veterans are proud of their military service, but in a new report published Wednesday, they expressed ambivalence about the wars in Afghanistan and Iraq.
In a new Pew Research Center report on war and sacrifice, half of post-9/11 veterans said the Afghanistan war has been worth fighting. Only 44% felt that way about Iraq, and one-third said both wars were worth the costs.
Some of those costs were outlined in the Pew study, which comes out as the United States marks the 10th anniversary Friday of the Afghanistan conflict, the longest-running war in the nation's history.
For instance, four of every 10 veterans reported they had difficulties adjusting back to life at home after the combat zone, and 37% said they suffered from post-traumatic stress, even though they might not have been formally diagnosed as such.
"The ambivalence that many post-9/11 veterans feel about their military mission has a parallel in the mixture of benefits and burdens they report having experienced since their return to civilian life," the report said.
