Sure... Obviously Adjust fire command really from my knowledge dont exist or didnt back then in Finland, since it means corrections anyway. For Talvisota its kinda hard since game is full of 1944 equipment anyway, but for infantry you can do it. Ill edit this once I get them sorted better. I think Reiter still gets the idea for most of them anyway so no need for all of them :). To be honest, those helmet decals werent that popular, one company used them duing Winter war but 99,9% cases no decals.
If you looking for info about Finns, check this site http://www.jaegerplatoon.net/MAIN.html it even has Finnish ORBATs of the era
3. Tuli seis
4. Tulitauko (Means the battery is on "break", before next fire request will come)
5. Tasalla (Means spotting rounds are on target, no need for adding or lowering. Fire for effect)
6. Tulikomentoja (different voice from the battery), basically means "fire commands"
7. Tulikomentoja (FO)
Correction on the colors for the clothing, they should be more gray.
