They aren't soldiers, full stop.
However, taking your assertions for the sake of argument and your previous statement of the 'militia' being effective at 'dealing with' the protestors (no evidence of that) would help Trump, then it would follow that you would think it acceptable and good tactics for the protestors/rioters/DNC/whatever to start killing the militia members.
But of course it wouldn't be for many reasons, the primary being that the general US public still holds black people and their allies to a higher standard than police, militias, and elected Republicans. Any real violence from them would be seen as them 'starting it' despite, you know, the police and the racists and their allies having been actually killing people, not just lately, but for decades.
