I was in the artillery. We would have been the ones training on delivery of chemical weapons (along with the Air Force). We did have special units who trained on nuclear artillery shells. I was unaware of any units trained on delivery of chemical weapons.
If Biden is going to reverse our policy on chemical weapons, he should probably notify the military, and maybe withdraw us from the conventions prohibiting the use of those weapons.
There is no way he knew what he was saying--his statement was nonsensical given the reality in which we exist. If I am to assume the best, then I must assume he meant something other than what he said. He must not have meant "in kind."
Or, if "in kind" meant "other unconventional weapons like nukes," that might make some sense. But, if he meant that, he should have said it. It has zero deterrent value if he is not clear on our intent to use nukes. He just puts us in an awful situation in which the other side isn't sure what he meant, and they think he probably meant something less than nukes, so they feel free to do what the want. Imbecile.
