This month, President Obama and members of NATO involved in Afghanistan formally agreed on a transition plan, preparing to hand over security responsibilities to Afghan forces by the summer of 2013. France's new president, François Hollande, restated an earlier pledge to remove all French combat forces from Afghanistan by the end of this year. Suicide bombings, IEDs, and a growing number of "green on blue" attacks (men in Afghan uniforms attacking coalition forces) continue to take a toll and limit security efforts. Gathered here are images of those involved in this conflict over the past month, as part of the ongoing series here on Afghanistan.
Dust lights up the rotors of a CH-47 Chinook helicopter as paratroopers with 3rd Squadron, 73rd Cavalry Regiment load for an air assault mission near Combat Outpost Ab Band in Ghazni province, Afghanistan, on May 23, 2012. Small sand particles striking titanium/nickel abrasion strips on the rotors causes a visible corona at night. In 2009, photographer Michael Yon dubbed this phenomenon the "Kopp-Etchells effect", to honor Cpl. Benjamin Kopp, and Cpl. Joseph Etchells, recently fallen American and British soldiers.

Cinema-goers watch a Bollywood film at Ariana Cinema in Kabul, on May 3, 2012. Once a treasured luxury for the elite, Afghan cinemas are dilapidated and reflect an industry on the brink of collapse from conflict and financial neglect. Kabul's cinemas show Pakistani films in Pashto, American action films and Bollywood to rowdy, largely unemployed crowds in pursuit of any distraction from their drab surroundings.

Farhad Saffi, the owner of Milli Boot Factory, stands in his closed factory in Kabul. Gazing glumly over millions of dollars worth of machinery which used to churn out thousands of police and army boots each day but now sits wreathed in plastic sheeting, Saffi fears he is seeing the death of an Afghan dream. Milli Boot Factory was a model for Afghanistan, showcasing local manufacturing while giving jobs to hundreds of people who may have otherwise have picked up insurgent guns. But a U.S. decision to hand procurement to the Afghan government has left Milli's owner with something of a developed world problem - local officials opted for cheaper boots made in China and Pakistan, killing off Milli's contracts after a year.

Wyatt McCain, 8, from North Pole, Alaska, sits beside his father's grave at the National Cemetery in Arlington, Virginia, on May 28, 2012 -- Memorial Day. His dad, Army SFC Johnathan McCain, was killed by a roadside bomb in Afghanistan in November of 2011. Wyatt came with his mother and three sisters to take part in a "Good Grief Camp". Five hundred military children and teens, many of whom had a parent that was killed in the Afghan and Iraq wars, attended the annual four-day camp in Arlington and Washington, DC, which is run by TAPS (Tragedy Assistance Program for Survivors). The camp helped them learn coping skills and build relationships so they know they are not alone in the grief of their loved one. They met others of their own age group, learned together and shared their feelings, both through group activities and one-on-one mentors, who are all active duty or former military service members. The TAPS slogan is "Remember the Love. Celebrate the Life. Share the Journey."
