> his won't kill Huawei at all

The goal isn't to kill Huawei... it's to make sure that Huawei 5G tech is delayed by 1 or 2 years. Banning their already-designed chips from shipping is a good way to delay them by a year or two.

Most of the USA doesn't even have 5G deployed yet, and the US is hoping local manufacturers will get the local market as well as lots of the world market.

US 5G manufacturers are already screwed due to US spectrum allocation, according to this DoD report.

TLDR: US spectrum allocation forces US 5G suppliers to design products primarily for the mmWave portion of the spectrum, which suffers from more technical problems such than the sub-6 GHz spectrum that Chinese products are using. The reason why the US didn't allocate more sub-6 GHz spectrum is because those frequencies are used by the US military.

It seems kind of silly that USA military would use tech that needs a pristine frequency band in the first place. During a war, are their opponents going to be super-polite about interference? Or, are they going to look at FCC regs when deciding which frequencies to jam?

Of course I have no idea about the real capabilities of that 6GHz equipment to use different bands in case of interference, that is most probably classified info. But economically, it would be silly to have all military equipment in continental U.S. work nominally on many different frequency bands. Likelihood of effective jamming of 6GHz bands in the U.S. is quite small (island with large area far away from enemies, low effective range of 6GHz radiation). Some systems have to be resilient against radio interference, such as attack warning systems or government - military com systems, but there is lot more in military - support systems, test systems, research systems, training systems and god knows what else.
