I don’t believe bowser even knows what crewed machine guns are... it would be some bloodthirsty Dem on her staff making that sort of request, IF, it even happened.
Guard units deploy in self contained units. So if an infantry guard unit deployed, they’d bring their gear and weapons.
They don’t show up somewhere via delta airlines, and then go looking around for a company or regimental store of weapons.
They bring what they need with them.
For break fix, etc, that’s when they go horse trading with other units/active, etc.
I heard there were Patriot missile batteries.
