From the Washington Post:
On a recent day in April, when U.S. aid officials flew to Lashkar Gah, the provincial capital, with several journalists, they were greeted on the tarmac by a commando-style security team that instructed the visitors on what to do if their vehicles were shot at or bombed, issued everyone flak jackets and closely guarded their convoy at every step.
When the group arrived at a tiny cucumber and eggplant patch, heavily armed Afghan and foreign security guards surrounded it. Later they fanned out across empty poppy fields, and stood guard along a dusty cobblestone road being built by former poppy farmers who are paid $4 per day by USAID.
