M*A*S*H was filmed on both an indoor and outdoor set. Although most outdoor shots were filmed on the outdoor set (the Fox Ranch) several were filmed on the indoor set, typically when timing constraints kept the outdoor set from being usable. Most of the standing sets were used in nearly every episodes -- the O.R., the Swamp, the office, the C.O.'s office. There were also a handful of sets that only appeared occasionally, like the kitchen, the library, the minefield.
It seems as if the main T-shaped building that houses the camp office, the C.O.'s office, the pre-op ward, the O.R. and the post-op ward is far too small to actually contain them all. Perhaps it is larger on the inside than on the outside. If not, chalk this minor issue up to the producers focusing more on the characters and the story than the logical layout of the camp.
Browse through the following list of tents and buildings that made up the 4077th campound.
The Swamp
Ah, the Swamp. Home to the surgeons of the 4077th, this tent was one of the cornerstones of the camp. When the series began, the Swamp bunked four surgeons: Hawkeye, Trapper, Frank and Spearchucker. After Spearchucker was written out of the series, only three surgeons were typically bunking in the Swamp. B.J. moved in when Trapper left and Charles when Frank left. Several times the screen walls were torn down or run through and the tent entirely collapsed on occasion.
The Operating Room (O.R.)
The O.R. was where the action happened, where the doctors and nurses of the 4077th performed meatball surgery in a desperate attempt to save lives. Wounded soldiers (and at times civilians) were brought in on stretchers and placed on one of several operating tables along the center of the room. Powerful lamps overhead -- when working -- illuminated the broken and battered bodies of the wounded and allowed the doctors to see what they were stiching together.
The Post-Op Ward
After surgery, patients were brought to the post-op ward to recover. A long room with beds on each side, it was staffed by nurses and a doctor on duty round the clock.
The Pre-Op Ward
While waiting for an operating table to open up in the O.R., the wounded were kept in the pre-op ward. Occasionally they never made it into surgery.
Commanding Officer's Office
Originally Henry's office, and later Potter's, the commanding officer's office (what a name) is where all manner of important paperwork is signed and important calls are made. Generals and colonels are brought to the C.O.'s office to meet the man in charge of the 4077th. There is also a cabinet full of booze, under lock and key, plenty of file cabinets, a big ole desk and when Potter was there, plenty of paintings on the walls.
Camp Office
The managerial center of the 4077th, the camp office was the only connection to the outside world via the telephone. Run by the company clerk (first Radar and then Klinger) the office recieved the mail, housed the P.A. system and kept an assortment of military and medical records. It was also where the company clerk bunked. It is connected to the commanding officer's office and the post-op ward.
Officers' (And Enlisted) Club
The Officers' Club was donated to the 4077th after Hawkeye and Trapper operated on and saved the life of a general's son (in "Officers Only"). Initially, it was reserved just for officers but Hawkeye and Trapper managed to throw open the doors to the club for the whole camp. In addition to a bar, the club holds a piano, several tables, a pinball machine and a jukebox.
Mess Tent
The mess tent was the main congregating area of the 4077th, large enough to comfortably hold the entire population of the camp (supposedly). Although primarily a dining hall, the mess tent was also used as a chapel (where Margaret was married), a movie theater, a bowling alley and an all-purpose party area.
Kitchen
Rarely seen, the kitchen is most likely connected to the mess tent in some fashion. Food -- or what passed for food at the 4077th -- was prepared at the kitchen and served to the camp at the mess tent. Lots of large pots and pans and bowls and ladles.
Scrub Room
Prior to entering the O.R. every doctor would methodically scrub their hands and arms before donning gloves, masks and the rest of their surgical garb. Located adjacent to the O.R., the scrub room had two large sinks, hooks on the walls for uniforms and various medical supplies.
Commanding Officer's Quarters
The commanding officer of the 4077th (first Colonel Blake and then Colonel Potter) needed his own private quarters where he could get away from the troubles of command and, in Henry's case, occasionally entertain a pretty nurse for an evening.
Margaret's Quarters
As head nurse, Margaret was afforded her own tent, which was good, because it gave her and Frank a chance to be alone. On the door was a sign with her name and the phrase "KNOCK BEFORE ENTERING."
Father Mulcahy's Quarters
Father Mulcahy, in his role as the camp's priest, needed a place where he could talk one-on-one with troubled souls. His door was always open and anyone in need of counseling was free to drop by, anytime. The sign on the door was shown both above and below the screen window, depending on the episode.
Klinger's Quarters
Why Klinger would be fortunate enough to have his own tent is a mystery -- but plenty of episodes showed him in his own quarters. Maybe nobody else would bunk with him. In any case, Klinger's quarters were full of his dresses, a sewing machine and other assorted Klinger oddities.
The Camp Library
Only seen in "M*A*S*H - The Pilot," the camp library was, as the name suggests, a tent housing a variety of books for use by the members of the 4077th.
X-Ray Room
Whenever a broken bone or misplaced shrapnel was suspected, wounded were rushed to the x-ray room for a dose of radiation. Often Klinger could be seen rushing into the O.R. with a freshly developed x-ray of a patient currently being operated on.
Nurses Quarters
Only four occupied this tent at any given time -- and there were more than four nurses on staff at the 4077th. So where do they bunk?
Supply Tent
Technically, the building holding the camp's supplies is more of a hut than a tent (I believe the proper name is Quonset hut), but the term "supply tent" wins out. Anyway, while the supply tent was supposed to be be used to store supplies, often it was used for a little fun. Enlisted men and doctors would bring a pretty nurse to the supply tent for a dinner date. Trapper and Margaret were once trapped inside while the camp was being shelled.
Ladies Showers
It seems unlikely that the 4077th would have two shower tents, so odds are when the ladies wanted their turn in the showers they simply put up a sign to keep all the men out -- except the ones they wanted inside.
Camp Showers
Despite the fact that early episodes showed the nurses having their own "Ladies Showers" (see above), later episodes saw a single set of showers with marked times for "Males" and "Nurses."
Latrines
The camp latrines were a dangerous place to visit -- over the years they were blown up, dragged away and run over by a tank. All in all, not the safest building in the compound.
V.I.P.'s Quarters
Very Important Persons visiting the 4077th were often bunked in the V.I.P.'s quarters so they could have a little privacy.
Motor Pool
The motor pool: where the jeeps and ambulances are kept -- and taken apart and put back together -- when not in use. During the last four seasons or so, Rizzo was in charge of the motor pool.
Animal Hutch
Radar kept a menagerie of little critters on camp, including rabbits and guinea pigs, all housed at the camp's animal hutch.
Bulletin Board
Located outside the camp office, the bulletin board was used to announce movie screenings, post important happenings, and even by Hawkeye to get a date. And, for some reason, ladies underthings were often pinned to it.
