Incapacitation is the goal, be that dead or simply unable to continue the fight but still alive. Most any centerfire rifle round will accomplish this. Lighter ammo means more chances and better control means better odds.
A couple of problems that we're running into with the idea of find and fix using ground forces and then calling in air to target and engage involve ROEs and urban environments. Such environments are "non-permissive" with regard to bringing the "big boom". In the open countryside that works great and we've proven that you don't even need ground troops. Light helicopters work great for "trolling" with the intent of drawing fire and calling in the hate from above. However, once you get into areas where collateral damage is deemed unacceptable, aerial bombardment becomes too indiscriminate. It comes down to the poor guy on the ground to handle the F2T2EA from start to finish. The big change from SE Asia is that troops aren't generally outside of immediate resupply and in an urban environment they are typically mechanized allowing them to carry significantly more or significantly heavier ammo than they would if relying on the heel-toe express for transport. With that in mind, a slightly more robust round would probably be a welcome addition.
