The bloody letter is still bright red: it would have oxidized by then and been rusty or dark brown.

When Lena finds Abram's grave, he is listed on the tombstone as a member of the 31st Fighter Group, 307th Fighter Squadron. However, the P-51 that appears flying belongs to the 325th Fighter Group "The Checkertail Clan" which was identified by the tails of its P-51s on a yellow and black checkerboard. On the other hand, both Fighter Groups were fighting over Italy and Southern Europe on those dates.

The 6888 Battalion were subjected to a bombing by the Germans. in late 1944. The last Glasgow and area bombing occurred on March 23, 1943.

Privates First Class Mary J. Barlow and Mary H. Bankston, and Sergeant Dolores M. Browne, were killed in a jeep accident on July 8, 1945, while on leave (liberty) in Rouen, France, while returning from a social event. They were not killed after driving over an unexploded bomb while driving an M35 "deuce and a half" cargo truck loaded with mail bags in Burmingham, England, as the film depicts. These three soldiers of the 6888th, and Elizabeth Richardson, a white Red Cross volunteer, are the only women buried at the American Cemetary in Normandy, France. The names of the deceased depicted in Perry's film are not the names of the actual soldiers killed.

Scottish police do not wear 'English' helmets, they wear caps.

P-51s weren't used for ground attack. In addition, the aircraft shown had no ground ordnance visible. They would not have been used when allied troops were actively moving across an open battlefield.

Modern U.S. currency is visible in the helmet when the unit is taking up a collection. Additionally, a $20 bill can be seen, which would be worth about $350 in 2024 - quite a generous donation.

The British 'square pin' plug was not introduced in the UK until 1949, but during the montage while the women are fixing up the school one is shown. Worse still, it's got shrouded pins which did not appear until the 1980's, and has a plastic body rather than period Bakelite. This is likely a contemporary 2020's 240v 13a plug.

The $20 bill placed in the hat wasn't introduced introduced until 1996 at the earliest.

There are many criticisms about historical inaccuracies in the depiction of the 6888th in the UK. While the 6888 arrived in Glasgow, they were stationed in Birmingham, England, not Scotland, police and military uniforms were from English rather than Scottish units. Additionally, while large-scale bombings had subsided by 1945, sporadic bomb threats, air raid sirens, and remnants of destruction were still present in Birmingham.

When Lt. Campbell walks into the barracks for the first meeting with the new 6888th recruits, her cap device (the eagle on the front of her hat) is upside down.

Lena Derriecott incorrectly introduces herself as being from Philadelphia rather than Pittsburgh. Bloomfield is a neighborhood there, and her mother and aunt were reading a Pittsburgh newspaper on their front porch.

Charity Adams tells the chaplain that she is the daughter of a preacher and knows the Bible "From Genesis to Revelations." Anyone with those credentials would know that the last book of the Bible is Revelation. Singular not plural.

The full name in the King James Bible is: "The Revelation of St. John the Divine." Other versions have slightly different names but they are all singular.

The two female officers are wearing their uniform caps while drinking in what appears to be an officer's club. Headgear of any kind is by tradition never worn in any military bar. Doing so incurs a fine of buying a round of drinks for everyone present.
