That’s a different thing entirely. Members of the US military don’t have combatant immunity when it comes to the US legal system, because what they are doing is legal in terms of the law. Combatant immunity would apply if they are captured as a POW by another nation following the Geneva conventions, which basically says that nation can’t charge them for acts of warfare, murder, etc. for participating in the war as a combatant. So long as they weren’t committing war crimes or something along those lines. So once again the President, as the commander in chief, doesn’t need immunity to order an airstrike or whatever, because it’s already legal for him/her to do so.
I feel lucky too. I have a 14900k that’s stable. I did have some minor stability issues after I built it, but dialing back the motherboard’s idiotic default settings plus a few BIOS updates cleared that up. With that said, if I had to do over, I’d build an AMD system. One of the big reasons I built Intel is that historically my Intel builds have been much more stable and less problematic than my AMD builds.
