I’m remiss for not mentioning, as Josh Foust does, that McChrystal has to answer for detainee abuse in Iraq, as well as the Pat Tillman scandal:

General McChrystal carries with him a dark side as well. One unit under his command, the now-notorious Task Force 6-26, which was assigned to find HVTs, or High Value Targets in Iraq, is credited with the ultimate death of Zarqawi. The problem is, along the way they faced accusations of running a secret camp that tortured prisoners, and they were implicated in at least two detainee deaths during torture sessions. Their camp, called Camp Nama, became something of a lightning rod after a “computer malfunction” destroyed upwards of 70% of their records and an investigation into their conduct stalled out.

More relevant to Afghanistan is GEN McChrystal’s involvement in the shameful coverup of Pat Tillman’s friendly-fire death. While he was named among the list of high-ranking military personnel believed to have covered up the circumstances of Tillman’s death, GEN McChrystal was “spared because he had apparently drafted a memo urging other officials to stop spreading the lie that Tillman died fighting the Taliban. He drafted that memo, however, after signing the award for Tillman’s posthumously-awarded Silver Star, the commendation for which claims, in part, that he was leading the charge against a Taliban assault. GEN McChrystal has never clarified why he signed an award for Tillman dying under enemy fire right before begging his colleagues and superiors to stop lying about Tillman dying under enemy fire.

In either case, GEN McChrystal’s appointment is a jarring shift for U.S. Forces in Afghanistan, which are currently transitioning commands between the 101st and 82nd Airborne Divisions.
