When Hawkeye tells General Clayton about Tuttle's accident and while delivering Tuttle's eulogy, there's a noticeable shadow on Hawkeye's face during the closeups which does not appear on any of the other actors in the scene. Hawkeye's closeup shots were obviously done on a soundstage at a later time and inserted into the scene.
When Radar enters Henry's tent to get some forms signed he makes reference to the stockings hanging on the line. There are light ones and dark ones there. When Radar is leaving the tent the dark ones are missing.
When General Clayton arrives, he salutes the camp personnel assembled before him and they return the salute, which is incorrect. When personnel are assembled in formation, the individual in charge should have called them to attention and then that individual alone would have given a salute on behalf of the entire formation.
Hawkeye creates Capt. Tuttle's personal file by handwriting it. But as an official U.S. Army document, Tuttle's file would have been typed, not handwritten.
In X-ray, when Maj. Burns believes he is addressing Capt. Tuttle (actually Radar in mask and faced away from him), Burns nervously refers to Tuttle multiple times as "Sir." Capt. Tuttle is, of course, a lower-ranking officer than Maj. Burns and thus doesn't rate being called "Sir."
It would have been impossible for Tuttle to have dog tags made without going through proper channels.
After his death announcement. General Clayton would have certainly looked at the dog tags allegedly owned by Tuttle.

Near the end of Hawkeye's eulogy, when everyone is saluting, the fingernails of Loretta Swit's right hand can be seen to be over an inch long. No nurse, especially a head nurse, would have fingernails that Long.
When creating a file for Captain Tuttle they decide he was born in 1924 and that he went to the Berlin Polytechnic. If Tuttle were born in 1924 he would have reached his college years in the early to mid-1940s making it very unlikely, as an American to attend a German college.
In the shots of Hawkeye after he has given Tuttle's dog tags to General Clayton, it is obvious by the lighting that Alan Alda is standing inside on a soundstage, while everyone else is outside.
Radar reads the comic book Captain Savage #10, which was issued January 1968, well after the Korean War armistice.
Captain Tuttle was supposedly 6'4", as indicated in the personnel file that Major Burns read.
So, later, Burns should have realized the much shorter man in x-ray, portrayed by Radar in a mask, was not Tuttle.
It would have made no sense to "make" Capt. Tuttle 6'4" -- a height that would have made him instantly conspicuous among the rest of the camp. Such a noticeable height would have quickly aroused the suspicion of those who would eventually be looking for him.
At the end, Radar, who later would rarely drink anything other than Grape Nehi, drinks with Hawkeye and Trapper. His character is more adult here than later on.
When accepting the large amount of back pay from the Finance Officer in the scrub room, Capt. Tuttle (Hawkeye in full surgical dress, including mask and gloves) first signs for the back pay and then takes the money in hand. (Soon after, he uses his hand to open the door to the operating room.) But a fully scrubbed surgeon would never touch such unsterilized items as a pen, money, or a door, even while wearing gloves, as it would require him to re-scrub and re-glove. The fact that Tuttle wasn't actually about to perform surgery is irrelevant, because the illusion that Tuttle was a conscientious and capable surgeon should have been maintained in front of the Finance Officer, lest suspicion be aroused.
