Campaign Challenge. A recurring event for the PG2 community. Campaign Challenges ("CC's") occur several times a year. The objective is fun. Several players play the same campaign simultaneously and post descriptions of the scenarios, in varying detail and styles, at JP's Panzers forum.
The After Action Reports ("AARs") can be as simple as posting the core army compostion using the Campaign Reporter tool, or can be humorous or serious descriptions of the action in the battles.
CC's are played at varying pretige levels by the participants, depending on the player's skill level and the general difficulty of the campaign.
By posting core compositions and AAR's the participants get to see how other players approach the game generally and particular battles.
