About Major Bartruff[]
The 4077th is caught in a crossfire between friendly and enemy artillery, and it gets so bad that Col. Potter calls I Corps to try and get them to stop firing.
Major Bartruff, who's the logistics officer at I Corps, really gives Colonel Potter a hard time, as he thinks that the 4077th is in another location, but Potter tries to tell them that they were there briefly, but are now back to their original location. They are "Mobile", after all.
Major Bartruff then asks for the proper code word to verify that Potter is who he says he is, but they have an out-of-date logistics book and I Corps rejects them, hanging up, not before Major Bartruff says to Potter, "Without the proper authorization response we have no way of knowing who you are. If you are one of us, get out of there; you're in danger. And if you're one of them stay right where you are, and we'll get to you, comrade!"
