Reading news like this reminds my of the famous Patton quote; 'I would rather have a German division in front of me than a French one behind me'.
"So, this is how I’m hearing that the attack happened this morning. A sergeant first class and a contractor approached an ANA checkpoint and struck up a conversation with the officer in charge of the outpost. In mid-sentence, the ANA officer shot the contractor and the sergeant first class, who went down returning fire.
As the sergeant first class was shot, the entire 17-man Afghan unit opened fire on the US convoy which was passing through the checkpoint. Three other soldiers were injured, and one is critical.
That means that there were 17 m’er f’ers who had slipped through the system that we were assured was in place to weed out the goat raping thugs who planned on killing Americans. 17 of them in one unit."
