To reflect the reality of war, a lot of nurses were cast on M*A*S*H, and they didn’t last long. They didn’t have large parts, so writers gave them bland names. The writers drew inspiration from the HAM operators and military, giving the nurses names from the phonetic alphabet. Kellye Nakahar, an actress who was frequently credited as Nurse Kellye, also appeared under other nurse names.
Nakahar was called Nurse Yamato, Nurse Charlie, and Nurse Able. Her role eventually expanded into a speaking part, with her most significant scene in the eleventh season where she got into an argument with Hawkeye.
Though the creators of M*A*S*H tried to remain authentic in their writing, there were nonetheless many inaccuracies. The boots worn by the actors weren’t actually army boots, as they were too loud. The boots were also notoriously uncomfortable for actors to wear, so most of them wore sneakers instead. Scenes were strategically shot to hide this.
Other inaccuracies included the use of aluminum cans, the pinball machine that was shown in the officer’s club, and candy bars with UPC codes printed on the back of them. All of these items were historically inaccurate, not created until the 1960s and 1970s.
