Not seen up close but definitely heard and discussed; Mulcahy's War has detailed talk and Point of View has the first person perspective of a soldier with a throat injury
There is one bit character who is on the spectrum at a higher support level, and while they don't state outright that he is autistic, they are exceedingly respectful in how they treat him. This is likely because William Christopher (Father Mulcahy) was an advocate for autism research, awareness and rights, due to his son being autistic.
A soldier is outed by men in his outfit, and the antagonist attempts to have him dishonorably discharged. The antagonist is a well known bigot, and everyone else believes he should leave the soldier alone.
Frank is the local bully, but he never attempts to physically beat anyone. However, he does accidentally shoot a fellow officer in the leg at one point.
A temporary POW holding pen is set up at the 4077 during the finale due to the number of North Korean and Chinese soldiers who keep surrendering at safe places.
Little Mac is a weighted dummy who helps a med evac chopper pilot keep his craft balanced when he's only delivering one patient. The dummy gets destroyed in a prank war between the doctors and Margaret.
A Korean baby whose father was American is left by the Swamp. The doctors quickly confirm that while she was abandoned, she was well cared for beforehand.
It's implied that Frank is at least emotionally abusive toward his wife and children, and he states that he was physically abused himself as a child. He also frequently abuses his rank and uses it to bully lower ranking officers. By the time he leaves, his entire character has become an example of the cycle of abuse and mental illness.
Hawkeye and Trapper gaslight Frank and Henry constantly in the first season. Frank deserves it though- they have to gaslight him as a nonviolent way to keep him from causing significant harm to others.
A character has an abusive father who she cries she's been disappointing him her whole life. Another character realises he was abused by another child. For both, nothing is actually shown.
Heavy reliance on alcohol throughout the series, mostly as an escape. One of the main characters turned to drugs at one point, but that addiction only lasted for one episode and was never brought up again.
A visiting female officer harasses a doctor, then accuses him of attempted rape when he doesn't reciprocate. Characters joke about him deserving this because of how disproportionate his own retributions toward his bunkmates are. Hawkeye complains at one point that he's never been violated at the local watering hole and says, "I don't know why I keep coming back."
Yes, but only kinda. A character threatens to by pouring "petrol" over himself and threatening to light himself on fire. Its a ploy to get discharged from the army. We find out that the "petrol" is actually water. This plan is foiled when they put real petrol in the canister. No one is actually hurt.
No, but one character pretends that he was injured by a jeep running over his head as a ploy to get out of the army. Its obvious that this didn't happen. You see a dented helmet.
In a season 9 episode, a main character gets a tooth knocked out by another character. In the next season, that same character has an abscessed tooth he's reluctant to treat.
The series' main protagonist is temporarily blinded by a malfunctioning stove. He meets a patient who has permanently lost his vision due to a battlefield injury.
It’s based on a Korean War field hospital, so there are scenes with blood and surgery. It’s never graphic, though. There are a couple instances of arterial spray.
The final episode has the main character suppressing a traumatic memory of a Korean mother smothering her baby to death because it wouldn't stop crying and possibly give their position away to enemy fire.
Colonel Henry Blake dies when his plane home is shot down (not shown, but is said when Radar reads a report of the accident to the OR) in the episode Abyssinia, Henry.
It is mentioned that Hawkeye’s mother and Radar’s father passed away when both were young children, and Korean orphans are featured in the show frequently. There is death of a parental figure in “Abyssinia, Henry” and “Goodbye Radar”
Kinda. A character who dresses in women’s clothes in an attempt to get a section 8 discharge is often called a transvestite, but the character is not transgender.
Perhaps the most overt instance is in season 7. A Swedish doctor mentions gender affirming surgery to Klinger, and he responds that you’d have to be crazy to do that.
Patrick Swayze guest stars as a patient who is diagnosed with leukemia. This may count as Harsher in Hindsight, as Swayze did die of pancreatic cancer a few decades later.
Frank is mentally ill and can be violent at times, though usually in a relatively harmless slapstick manner. But he gets dangerously violent off screen in the opener for season 6 and is granted a section 8 discharge. In another episode, Klinger has to deal with a bunkmate who seems to experience hallucinations. The guy even starts shooting at them.
There is an episode that features a soldier who is on the spectrum and sticks close to his injured caregiver. He is zealously protected by his companions. It could be argued that the army is exploiting him by not making him 4F, but he is never abused outright.
In one episode, there is a patient who has been refusing to eat since his friends were killed. The subject is treated seriously, and a psychologist trys to help.
not on screen but it is mentioned in “Dear Sigmund” that one of Sidney’s patients died this way. There are a couple episodes where patients express ideation
PTSD is addressed in the context of 1950s psychiatry multiple times, but is most prominent in the finale when the main protagonist suffers a breakdown due to it.
Abortion is mentioned as a serious option when a female character thinks she may be pregnant. The character wants an army career over having a child (being preganant means instant discharge from the army). The character ends up not pregnant. The character is treated seriously and isn't mocked.
A pregnant woman is injured in one episode and has to undergo an emergency cesarean. Fortunately, she was already full term, and both mother and baby end up being perfectly fine.
Frank is occasionally ignorantly insensitive toward Sidney Freedman, the on-call psychiatrist who is ambiguously Jewish, but at no point are Jews actively stereotyped, insulted or treated as less than human.
A running gag involves one male character wearing dresses around the base in an attempt to get discharged and sent home. However this never works, and in one instance he was saluted by a general he intended to offend by dressing up as Lady Liberty.
Worth noting that appearances of this character is accompanied by a laugh track but the in-show characters don't get offended or laugh at his appearance (except for one who is portrayed as an unlikable bigot). The laugh track can be turned off in the DVD version of the show.
Tommy Gillis from Sometimes You Hear The Bullet is heavily implied to be queer (he kisses a man on the mouth on screen, but it could be argued to be a joke I guess) and he dies in the same episode.
Acephobia. Aphobia is a LACK of fear. Anyway, Father Mulcahy all but states outright in more than one episode that he is asexual. This does not stop one nurse in particular for coming onto him, then she blames him for not reciprocating. The camp CO scolds him instead of hearing his side.
The antagonist of the first five seasons, Frank, is portrayed as a bigot and tries to get a gay soldier discharged from the army in one episode. This is painted in a bad light. Hawkeye ultimately thwarts Frank's plan by blackmailing him.
Hawkeye and Trapper deal with a racist patient by pretending to give him "black" blood, then painting his skin dark to make him think he's turning black.
More of a bittersweet ending. The war ended and everyone finally got to go home, but not without being irrevocably changed and affected by their experiences.
“I have a message… Lieutenant Colonel Henry Blake’s plane… was shot down over the Sea of Japan… It spun in… There were no survivors.”
Truly one of the show’s most memorable and most heartbreaking moments.
In one episode there is a korean (Whiplash?) who throws himself in front of jeeps for the blackmail money. This happens twice. Whiplash acts badly injured but isn't really. The medical unit takes care of him anyway.
