As was mentioned last time this was posted, it’s a matter of being able to use gas masks properly. If the masks don’t form a seal with the skin the wearer is dead.
When was the last time the US fought an enemy with a credible chemical stockpile? That’s why it hasn’t been important the last 30years. But Russia has shown to still possess chemical weapons and the will to use them. North Korea is known to have CW in their arsenal, and it would be naïve to assume that the PRC doesn’t.
At the moment allies for WW3 are still blurry, but I guess it’s better safe than sorry. So it’s not a rule intentionally targeting black people, it’s protecting all soldiers. The rest of NATO should probably enforce the same rule.
What a mighty warrior, he’d be dead with the first chemical strike.
