The National Guard Transportation Corps does have units qualified to load and unload container ships that can be called up in the event of a true emergency, but I doubt this qualifies. They still have regular full-time jobs. The active duty military can't be used for something like this unless we're actually at war. Of course, me saying I "doubt" this qualifies is a personal opinion. As far as I know, it's pretty much up to the governor of each state to decide what counts as an emergency worthy of activating the Guard. I don't think it's ever been done as a response to somewhat higher than average inflation rates, though. It's usually natural disasters and long-running riots that the police can't control.
