I responded above I hope that provides enough. Though I didn’t speak to article a).
It may sound like a legal cop-out but some countries make a distinction between “The Red Cross” and “a red Cross”. It’s a weird one. Probably requires more scrutiny.
And as to your question of “Would this be a crime committed in war?” Or “A war crime?” That’s where lots of legalese comes in. It may be that one nation sees it as a crime where one doesn’t. Or the UN finds it a war crime but another organisation doesn’t or is a partial signatory or conscious observer and so on.
This is then something I understand is moved into the restitution phase post war where both nations sit at the table and dole out various legal requirements, PW transfers and the likes. Like a two sided lawsuit but instead of just money it’s money and human lives.
Which is nice.
I’m glad I could be of a little help. Nations have been trying to clearly define these things for centuries.
I think your final statement is why I’m here. A lot of internet discourse around war immediately resorts to calling everything a war crime. That’s an incredibly precise label and we can’t always be certain. What I know for sure is that war is hell and undue suffering is wrong.
