Character mistake: In the scene where Captain Sobel is inspecting the soldiers at the beginning of the episode, he goes up to Sergeant Lipton and notices something wrong with his chevrons. Well, in that part, Sergeant Lipton is not standing correctly in the position of attention because he is sort of slouching and his head is in front of his shoulders and the correct position of attention is standing straight up and having your neck behind your shoulders. If he was in the real army, he would have gotten a punishment for not standing at the correct position of attention. (00:09:30)

Character mistake: Winter calls his officer Major Strayers, when actually Strayers was a Lt Colonel. Winters made the same mistake in Currahee when walking upstairs with Capt Sobel.
Suggested correction: Strayer didn't become a Lt. Colonel until 1945. In fact, Winters took over leading 2nd battalion of the 506th from Major Strayer when he became a Major and Strayer was promoted to lead the regiment.
