When it comes to counter-insurgencies run well over history, they always tend to move out of the military solutions and into the civil/governance solutions. Military soldiers are trained to fight and maneuver, hypothetically PRT representatives, NGOs and diplomats are trained in governance. So, while PRTs are not a model of what to do, they are the best we have.

To point at one solution, for not modelling off PRTs, picking up inactive ready reservists and training them for a few weeks in civil affairs will not make motivated soldiers for governance.
