The Green Berets’ job is not to actually do the bulk of the fighting but to make alliances with local villagers and train THEM to fight. It worked well in late 2001 and early 2002, but apparently those guys were pulled out of Afghanistan and sent to Iraq when the insurgency broke out there in 2003. Good news that they’re going back to take on the revived Taliban.
Each SF Group is tasked to a particular region of the world so that they may learn the language & culture that they will be dealing with. The problem is that the 5th SF Group normally tasked to cover Afghanistan is the same one that covers the Mid-East (Iraq). These troops have been on a deployment merry go-round since 2001. Other Groups have tried to cover, but they lack the language skills for the most part.
