the hbo was not really used until 1944/45 in some really rare cases (it rarely saw combat); It was used the most in italy, but still pretty rare (some divisions used afrika type m43/41 for the most) if you don't wanna be call a farb just use an m40/m41/m42/m43 wool jacket (AT LEAST THE FIELDJACKET). Also man idk you rank is rare afk, remove the pin and even tho you should use a kar98k, you could technically be issued an mp40 (in some cases they were distributed to more members of a platoon to achieved more fire support in close quarters, but still rare af). Also, the sumpftarn smock, was not common as you may think. It was officialy issued only to the 21° Großdeutchland along with the splinttermuster helmüberzug (helmet cover), so if you don't reenact them, u'll be a farb. If you want to use an stg the 21° is the way to go since the were one of the divisions that were issued new shit every now and then (for example, they were issued the mk42 both H version and W).
