The personal military staff of the Governor shall consist of one officer with the rank of colonel and as many other officers as the Governor may consider appropriate with the rank of lieutenant colonel or commander, all of whom shall be appointed and commissioned by the Governor and shall hold office at his pleasure. All such officers shall be commissioned in the State Militia as aides-de-camp to the Governor, but no such officer shall be barred, by reason of being a member of the staff, from holding an active commission in the Alabama National Guard or the Alabama State Guard or a reserve commission in the Armed Forces of the United States or any civil office or employment under this state or any agency or political subdivision thereof. No member of the staff shall by virtue of such membership exercise any command or control over any part of the Alabama National Guard.
