First we have Panzer Corps 1 Grand Campaign:
https://steamcommunity.com/sharedfiles/ ... 2410075863
which is the grand campaign for Panzer Corps 1 remade for Panzer Corps 2 by a group of six fans (Ezequiel Romanko, Rick Kesler, Davidson, Grondel, R2G2 and Swifty).
It’s a large mod, and the most downloaded on the whole of the Workshop. It is currently playable up to 1943, and development is still ongoing.

On second position, here’s the New Units Pack:

which adds 10 new german units to the game, including the Command Panzer A, the BF110 Heavy Fighters and the Fallschirm sPzB 41 (airborne anti-tank). It’s developed by one of the authors of the Panzer Corps 1 Grand Campaign remake, R2G2.

The third most downloaded mod is The Big Red One:
https://steamcommunity.com/sharedfiles/ ... earchtext=
a campaign comprising of 15 custom made missions following and detailing the chronicles of the Big Red One (1st Infantry Division) as they fought from the dunes of Africa to the end of the war in Germany in 1945. This is also developed by one of the authors of the Panzer Corps 1 Grand Campaign remake, Davidson.
