It's a threat to say if they try to remove him he has people that can kill you on his side. The thing that has to be kept in mind here is 70% of the population does not support him. However, like 80% of Republicans are still supporting him...which is nuts but whatever. The projection there is there may be about 22% of his voters that actually believe anything this guy says and may react violently if he is charged for his criminal activities. That 22% is a small segment of the population but it is enough people that if he is successful in encouraging them to respond with violence a lot of people are going to get hurt/killed. Make no mistake, that's what he is doing.

I wonder if Marc is keeping his gun well oiled for the coming revolution?

The truth is I do not think he has the military on his side, military leaders have continuously spoken out against him. Law enforcement people also do not seem to be on his side either. So, he is blowing smoke.

Why does he lump the police and military in with Bikers for Trump?

Well, yes because he's an idiot but that denigrates the military and law enforcement.
