Peak Reality Check

Is refusing a direct order affect the readiness of a military unit? Does military readiness take precedence? Medical readiness? Could those objectors fall under a certain political philosophy that is NOT compatible with a military organization? Are local churches connected to Militia groups? Armchair constitutionalists. Are these people who cannot see the future and want to live some fantasy thinking that things will be ok with a oligarch/theological leadership? Can you name a country that has survived under an oligarch/theological leadership that benefited its people?
