Liberal Gun Owners

Just to expand on that, there's value in just having them. The US military has developed anti-insurgent tactics over the past 20 years. One of them is that to occupy an armed populace, they expect to need one soldier for every three civilians in the area. They have to assume everyone is armed and everyone will be against them.

That would mean that if they want to put the US under martial law, they will need to mobilize 25% of the US population into the military directly and expect them to follow orders to the same level of competence as the existing military. This is a pipe dream. Approximately 10% of the US population was uniformed up in WW2, and agreement on the war was nearly universal. The draft existed not so much to get enough people, but to make sure the military could take in people at a sustainable rate without cutting too much into industrial production at home.

All combined, the regular military, the National Guard, and ICE do not have enough people to put the entire country under martial law. They don't even have enough to put New York under martial law. They might have enough for Vermont. The ICE recruiting surge won't change this.
