Around-the-clock bombing, missile and artillery strikes, and deep insertion of covert assets are not US/NATO doctrine? Did I watch a different invasion of Iraq than you?
Edit: If you're objecting to HALO insertion as a measure against AA then fine but even describe as a way around AA:
"The technique is used to airdrop supplies, equipment, or personnel at high altitudes, where aircraft can fly above surface-to-air missile (SAM) engagement levels through enemy skies without posing a threat to the transport or load. In the event that anti-aircraft cannons are active near the drop zone, the HALO technique also minimizes the parachutist's exposure to flak...
... The combination of high downward speed, minimal forward airspeed, and the use of only small amounts of metal helps to defeat radar and reduces the amount of time a parachute might be visible to ground observers, enabling a stealthy insertion."
Edit: I don't understand why you're fixated on one or two options being insufficient for certain scenarios out of a redundant number of options at the U.S. disposal but whatever.
Like HALO is the only way to insert a team? You're clearly not clueless about a variety of tactics so I'm confused why you're not extending that here.
1. Round the clock bombing. We saw how F-117, flying the same route day after day in Serbia was shot down by an S-75 Dvina (first deployed in 1957) in optical mode. You will never see a B-2 flying in daylight any more than you would see an AC130.
2. What US artillery can outrange an S300/S400? US artillery is already outranged by Russian artillery.
3. Missile strikes are the only thing you list that are even doctrinal against a modern A2AD system. And those are limited, as NATO found out when several members ran out of smart munitions when overthrowing Qaddafi. But yes, that's what we'd use. JASSM, Tomahawk, SCALP, etc.
4. Using Iraq as a measure of how we'd fight a near peer opponent is ridiculous. While Iraq had a large standing army, it was never a match for the US in 1991, much less 2003. There are numerous things we did in Iraq that we'd never have attempted in the Fulda Gap.
5. Finally, back to HALO. Sure the operator jumping out using HALO might have a minimized signature, but remember that big, lumbering transport that he's jumping out of? The one with the ginormous radar signature? Flying high (so the H in HALO) can occur, meaning every radar in the world can spot it? BOOM. Shot down as soon as it's in range of an S400. Which is roughly between 300 and 400KM. So if you're expecting a team dropping in by HALO to survive, you're delusional.
