Why do player aids say nothing about one less Barrage CP when in Hindenburg Line and nothing about +1 to AV when tanks are leading the attack? Why areas which are barraged in impulse 0 on Nov 20th are not marked with a symbol thanks to which you wouldn't have to page the rulebook to find an appropriate section?
An OK game but QA-wise and graphic-design-wise, it is no good.
1. These are special as opposed to general rules and the card is meant to depict general rules, with the assumption the player has read the rulebook and knows about these early game exceptions. Looking at the card, also, I suspect space was an issue.
2. Marking the map with information that applies only to the first game turn would be rather distracting thereafter. Also, same issue: the player is assumed to have read the rules, which are not overly long or burdensome.
