My brother has been stationed with these guys for the last year in Panjshir, Afghanistan. There was a group of 10 guys stationed at this base training the local police force. My brother with 8 others departed for home around June 20th. These 2 guys were left behind for a few more weeks and then were to be shipped home also. From what I heard, they stopped to see if a local man on the road side needed help and he opened fire on them.
