Notice how quickly Mathews ended the discussion as soon as the Colonel asked about him still being on the military's payroll. And what is it with these leftists that cannot have an honest debate without talking all over the other person. No dissent allowed. Yes, sounds like socialism/communism to me.
The part about still receiving a pay check was never answered. If he is not , he probably is in the inactive reserves, which means he does not go to monthly drills.
If he is receiving a pay check then he is in a specific Guard or Reserve unit. He states that he is a Captain, so he could possibly be a Company Commander. As a former Guardsman, I find his behavior very divisive to any unit he may be assigned to.
