Afghanistan is not Iraq,the model for the successes there does not apply. The taliban on numerous occasions have decided to slug it out with Coalition Forces, this is not a traditional COIN environment,the big hammer is required more often than not,this has been shown time and time again.
Rolling around in a LAV dropping JDAMS has provided the security environment to allow GoA to begin projecting force and conducting operations, scaled back operations would have us back in the situation we faced in 2006 with the taliban/bad guys poised to attack Kandahar City.
I agree 100% with the need for a dedicated DMR rifle,we need to take a serious look at replacing the current weapons and developing a doctrine and training system for prospective DM.
