We have the Iran fight coming up and there are advocates for “boots on the ground” as being sufficient? or eeven a large component? We do not have and do not have the prospect of having sufficient boots for this concept to be viable beyond specialized applications.
Next time boots on the ground are called for it will be the USAF that softens the targets and claims the sky (while waiting for the Navy to arrive) so marines and the army survive long enough to engage. If China gets bold to the west it will be the USAF that will make them think twice.
America has dominance in the seas, in the sky and on the ground - the only place we don't do so well is with the policy makers.
