>where GPS isn't guaranteed, a
why would the US not have GPS when they literally launched the GPS satellite network that half the planet uses?
>and where air support isn't guaranteed
why wouldnt the US have air support when they have the largest airforce in the world and have put a lot of time and resources to ensure that air superiority can be achieved on day 0?
>And where being able to send in armoured support right on the front isn't guaranteed?
why wouldnt the US have armored units deployed when they have poured an untold amount of money into making sure they have force projection?
this is like asking how the soviets would win WW2 if they didnt have artillery superiority
>and they are totally unprepared to handle a near peer adversary.
first of all, what near peer?
second of all, like all other countries, if they cannot secure air superiority before the ground invasion, they would instead operate closer within where air power can be brought to bear
you essentially put the cart before the horse, the US doesnt send troops in and then take air superiority, they will take air superiority and then send troops in
any area where the enemy can take and maintain air superiority is an area that the US airforce will avoid and instead try to deplete enemy air assets elsewhere
this is the same as asking how a soviet army how they would take an area where they dont have artillery support; they wont, they will instead operate in areas where artillery is available and attrite enemy artillery there
