I doubt he'd set foot in Afghanistan. It could simply be their general mission was to track him, the Doc and others, but it involved many tactical operations in order to capture/kill/track various terrorists.
I wish they didn't release any of this. Maybe they should've 'hidden' this as 2 soldiers KIA in Afganistan.
Because now the Taliban/Al Qaeda, if they didn't know it before, know we have small teams in Pakistan hunting for them. Now they know what to look out for.
I would not have disclosed their mention.
