Members of the military have an obligation to refuse illegal orders. I am neither in the military nor a lawyer, so I can’t go too deep on that.
I have no doubt this is his first step in ferreting out any military leadership who holds loyalty to the constitution over him personally. Whether this particular plan is blocked or not, it lets him clear out anyone who won’t follow his orders without question going forward.
Even if we see (likely) “act first, let it wind through the courts later,” I’d expect there to be a substantial number of refusals.
