For Moscow the bottom coat with red collar (the middle coat works for Moscow too). For Stalingrad the top coat with green/khaki collar. (Based on my understanding, I could be wrong)
The color of the coat doesn’t matter. Just the color of the collar/shoulder patches (shoulder patches aren’t modeled on these for whatever reason)
it depends. technically, all.
first one is based on the enlisted coats, earlier versions.
the second one, is based on radiomen or, it’s supposed to be an officer coat.
( unsure due to being… semi fictional )
last one, it’s part of, or inspired to NKVD units.
Oof I guess I was very wrong then. I thought the bottom one had early war infantry collar (red), the middle one had artillery collar (black with red), and the top was infantry but with subdued color change around late 1941.
well, i can’t really blaime you for " getting them " wrong.
to be fair, they are somewhat fictional or rather, inspired. ( due to being old ).
these are the same models still used since the alpha.
with that being said, i’m somewhat familiar with them as i spend most of the time in the editor.
nametags etc reveals some details etc. 
I guess first one is the safest, right?
yes
Noted, thanks friend
always a pleasure.
after all… cosmetics are what keeps me going in this game 
I am really hoping that they will release mortar squad Normandy uniform for all squads and theaters alongside the grey pilot trousers. I really really want to dress up these little dudes with FJ uniforms but for some ungodly reason DF decided to gatekeep uniforms across campaigns and squads. I really hope one day they will all just release all TT squad cosmetics for all theater and squads.
that’s HORRIBLE, they did war crimes you know?, they shouldn’t allow it or some people will cry about it! sarcasm meter in red levels
i sometimes wonder if you are actually playing barbie with guns…
Spoiler
that’s precisely what i do in the editor
except, are all Kens.
