Any citizen of this state may hold a commission in the militia of this state, the national guard of the United States, or any active or reserve component of the United States armed forces without thereby vacating any civil office, position, or commission held by that citizen. The holding of any commission shall not constitute such a holding of an office of trust and profit under the government of this state or of the United States as shall be incompatible with the holding of any civil office, position, or commission under the government of this state.
