Nicholas Schmidle at The New Yorker on the raid to get Osama bin Laden. An excerpt:
On April 18th, the DEVGRU squad flew to Nevada for another week of rehearsals. The practice site was a large government-owned stretch of desert with an elevation equivalent to the area surrounding Abbottabad. An extant building served as bin Laden’s house. Aircrews plotted out a path that paralleled the flight from Jalalabad to Abbottabad. Each night after sundown, drills commenced. Twelve SEALs, including Mark, boarded helo one. Eleven SEALs, Ahmed, and Cairo boarded helo two. The pilots flew in the dark, arrived at the simulated compound, and settled into a hover while the SEALs fast-roped down. Not everyone on the team was accustomed to helicopter assaults. Ahmed had been pulled from a desk job for the mission and had never descended a fast rope. He quickly learned the technique.
