Yes, that is why the Russian war has so shaken artillery stocks, Ukraine can’t fight like NATO/US so they need the old
ways.
The Marines are not disarming themselves they are differently arming themselves to fight China.
The problem is that the Maries hope “it will be different this time”. And most likely it won’t.
That Jimmy Thomas video actually had footage from The Thin Red Line as one of the few movies where they (somewhat) realistically show artillery fire and correction. So that was US Marines against the Japanese.
For US Marines against China. Most likely it will be the same.
Betting that it will be different - if that is wrong, US Marines will be destroyed and lose.
