I finished the Campaign finaly. The scenarios were quite challenging to me but there were some easy ones too. I used up all my repair points but never managed to fix all the units in the core force. It might have been good to give 200 or even 250 repair points after the battle at Brest. That way the player would have enough points to reapair the whole core force and possibly upgrade some units to different ones. Or then its just me sucking at this game.
The last mission of this campaign was also very hard. I noticed that the map had been set to Winter status so the infantry moved quite slow. With the mud and mine fields I could not capture all the victory locations in time and the battle ended in a draw.
I think the best strategy for that final scenario would probably be to attack the Southern bridgehead with one comapany and the Northen one with two. Still A dificult task with the slow movement, mines and heavy enemy artillery. I will have to try it again someday.
All in all I did enjoy this campaign it was difficult but fun.
