Henry holds up a little doll from his desk, saying, "I got this little outfit at the Tokyo PX last week," as if it's a new thing. But that little doll has been on his desk (or at least visible in his office) right from the beginning of the series.
When Henry is sitting at his desk playing with the Japanese doll, his cigar jumps from his mouth to his left hand depending upon the angle of the shot.
when Burns and Henry are in his office talking Henry holds the doll with his right hand but at the end he puts it down with his left hand while he picks up his lighter with his right hand.
(at around 2 mins) When Hawkeye and Trapper are getting ready in their tent to go see Charlie, Margaret is helping Frank put on his gun belt. When the belt is placed around Frank's waist the belt is twisted, but in the next shot the belt is fine.
After Henry gets off the phone with General Clayton he starts counting his winnings.
But in the next scene he has his arm that is holding the money on his desk but in the next scene he is counting his winnings again.

While in his office with Frank, Henry hears from Radar that he won the daily betting pool with a bet of 75 1/2 yards. Radar then states that Corp. Johnson came in second with 22 3/4, but earlier Henry was operating with Ginger and told her that her "number" of 32 1/2 yards was way off. When General Clayton returns Henry's call, Henry tells the General that his bet of 52 yards was a "little short." Also, when Radar collects money from Trapper and Hawkeye, their distances are 47 and 62 yards respectively. All the bets that were heard about should have been well ahead of Corp. Johnson's "second place" guess of 22 3/4 yards.
The 3"/23 caliber gun that was loaned to Frank was actually a deck-mounted Navy gun that was not engineered for ground use. When World War II began, the 3"/23 caliber gun was outdated and used only used on submarine chasers and various auxiliaries.
When Henry is ordering a gun on the phone, he says "nug" because he's holding the book upside down. Actually "gun" upside down would look more like "unb".
The 40mm gun Burns is given is really a Navy 3"/23 calibre gun. However, it is only referred to as a 40mm when Frank requests it: It clearly was not what was actually requisitioned or supplied.
Charlie's bomb blows up General Clayton's jeep. You can clearly see that the jeep is already mangled and charred before the jeep goes up in flames.
When the anti-aircraft gun is fired it makes a direct hit on the ammo dump. Given the trajectory and distance from the dump, the round would have impacted much higher on the hill behind the dump.
Frank mentions Billy Mitchell, saying he was played by Gary Cooper. Gary Cooper starred in "The Court-Martial of Billy Mitchell" in 1955, two years after the Korean War ended.
The Wall Street Journal that Trapper is reading is the current 70s version, not the version of the paper circulated in the 1950s.
The aircraft used to depict "5 O'clock Charlie's" plane has two seats, one behind the other, and is flown from the rearmost position. The pilot of the aircraft is visible crouching down in the rear in several shots.
Even with as easygoing a commanding officer as Col. Blake, he would not permit Capt. Cardozo (the guitarist in the Swamp) to wear a beard.
