1 - his combat power - the combat power of the enemy is people. They have AKs, some machine guns, RPGs, and explosives. There are no planes, tanks, howitzers, fuel trucks, etc. You have to kill the right people. This means intelligence. Not SIGINT, but HUMINT, and the only way to get that is through the local population. The only way the locals feel secure enough to tell you is if you secure the population. Classic counterinsurgency. More troops can help with this.
2 - Constantly seek out and destroy the enemy on his own turf - the reality is that the enemy has sanctuaries in Pakistan. How do we eliminate the sanctuaries? Critical to success. More troops does NOT help this situation. So how do we deal with these?
