just a reminder that the US never lost a single battle during the entirety of the Afghan war.They already mastered their ground warfare.
winning wars=/=winning battles
we'll see how the Taliban maintain control on the countryside and in urban centers, while combating Panjshir militia, ISKP and maybe possible disgruntled islamist group like ETIM (after the IEA ensure China the cooperation they need). As history always suggest, it's not an Afghan thing to be ruled centrally. Not the Communists, not Karzai/Ghani and certainly no the Taliban.
plus, those 75K strong Taliban soldier will likely be demobilized soon, meaning less troops could be deployed. Less troops=more rapid deployment needed.
more rapid deployment = more choppers.
