Thank you. I could say I have little knowledge about submarines and their crews, especially foreign ones, so I've run into one problem.
I wrote a code for crew leveling system, in which once submarine gains a level, a random crew division(?) gains a point and corresponding bonus is applied. On russian ships those divisions are called "boevaya chast'"(боевая часть). I'm using 4 out of 7:
boevaya chast-1 Navigation
boevaya chast-3 Mine/Torpedo Weapons
boevaya chast-5 Electromechanical
boevaya chast-7 Radio engineering

So question is how can I call those divisions(?) in human English)? What similar divisions are on US subs and how do they called?

How it will look ingame:

P.S It seems that forum do not accept images from LightShot's server, and I do not really want to use an image hosting... So direct links instead of images...
