It's not obvious to me.

From the marine corps regulations on smoking



6. Policy. It is Marine Corps policy to discourage the use of
tobacco products, to protect all personnel from exposure to ETS
to the greatest extent possible, and to provide users of
tobacco products with encouragement and professional assistance
in stopping their dependency on tobacco products. The
objective is to establish a safe, healthy, and "tobacco/ smoke
free" environment for all personnel.


a. Smoking is prohibited in Marine Corps occupied
buildings and facilities as noted below:

(1) Base Family Housing. In the common areas of
multiple family units.


(2) Auditoriums and Theaters.
(3) Conference Rooms, Classrooms, and Libraries.
(4) Elevators.
(5) Official Buses, Vans, and Shuttle Vehicles.
(6) Gymnasiums and Youth Activity Centers.
(7) Child Care Centers.
(8) Family Day Care Homes. Smoking in Family Day Care
Homes shall not be permitted when children, other than the
provider's own, are present unless the parents of those
children voluntarily consent thereto in writing.


(9) Work Areas. Indoor work areas where a central air
system is in use. Commanding officers may allow smoking in
private offices only if that office meets the ventilation
criteria described under paragraph 3f of this Order. In common
work areas, without a central air system, space may be planned
to accommodate the preferences of smokers and nonsmokers
provided that:


(a) Efficiency of work units will not be
impaired.


(b) Additional space or costly alterations will
not be required.


(10) Barracks. Smoking and nonsmoking preference
shall be considered in the assignment of barracks berthing
space. There shall be no smoking in BOQ/ BEQ rooms or squadbays
shared by smokers and nonsmokers. When it is impractical to
segregate smokers and nonsmokers, smoking is prohibited. In
barracks which have a central ventilation system smoking is
prohibited.


(11) Corridors, Lobbies, and Restrooms. Corridors,
lobbies, and restrooms shall be designated as no-smoking areas
unless they are well ventilated, are not supplied by central
air, and are designated as a smoking area by the commanding
officer.


b. Commanding officers may designate and post smoking
areas, as necessary, in all eating facilities under Marine
Corps control. Smoking areas shall be permitted only if
adequate space is available for nonsmokers and ventilation is

adequate to provide them a healthy environment. These areas
must be clearly marked as a "SMOKING DESIGNATED AREA."


c. Smoking on aircraft shall be regulated by the
operational directive for each aircraft type and as required by
Federal law.


d. Within medical treatment facilities, smoking is
prohibited. All medical treatment facilities will be
designated as "smoke free" facilities.


7. Action. To create a social environment that supports a
abstinence and discourages use of tobacco products, and to
enforce the restrictions on smoking in Marine Corps occupied
buildings and facilities the following actions are directed:


a. The CMC (MH) will:

I see nothing about banning smoking in any of those regulations.
I see prohibitions against smoking in specified areas. Those have been in place since, at least, 1980 when I joined the service.
All it basically says is that there must be enough ventilation.

That's a lot more lenient on smoking than the states are trying to make the places here. It doesn't look to me like they have any intention of banning it altogether. It looks like they have every intention of providing a place where both smokers and non-smokers are comfortable.
