To add to Bob's comments, the GPF needs training to perform the kind of operations SOF need in conjunction with their efforts. If the SOF teams take the lead in disaggregatating tribal leadership from an insurgency, they need GPF troops to come in and provide security, training, medical clinic, infrastructure improvement, etc. I.e., all the things necessary to ensure the SOF efforts continue to bear fruit, but the SOF don't have the manpower or TOE to execute.
