Of course military and incarceration issues are in the Constitution.
Tell me where are the enumerated powers the Constitution delegates to the feds to meddle in your health, your drugs, energy, the environment, abortion, race, gender, etc., etc., ad infinitum, ad nauseam?
Why are you defending a mostly unconstitutional totalitarian federal government that is one election away from destroying your country, your freedom, and your life as you know it?
Hence the mention of an army and a navy. If we're talking that only explicit powers are listed in the Constitution then an Air Force and a Space Force are missing. Along with the other organizations I mentioned.
