I'd come out of the army after five years as a medic. I was a medical administrator and we ran hospitals, and I was a Captain in the army at the end, in 1945. ↗
However, most of my part, I play a pediatrician, and most of my role had to do with being in another place, staying at the hospital and trying to save kids and stay until people could come. So, it was more based on reality. ↗
