Nobody knows what's going to happen, and I'm no military expert, but I'm thinking the military's role does not include arresting those who commit election fraud.

Martial law can be instituted, and we would have the military take charge, but it would have to be declared by the president; and he's not in office right now, since it was stolen from him. The walking, talking ostomy bag currently pretending to be Joe Biden isn't going to declare it.
