Another confusion: Page 36 defines Grand Batteries, but I cannot see what they are supposed to be in the rules.
I found this! Although Grand batteries are in the advanced rules, the rules for what they do are in the standard rules!
Another find - right at the very end of the last phase of the turn(combat) there is a paragraph stating that unit status improves automatically at the end of the
command phase, which is the first phase! Not sure if this is a typo and units improve at the end of the combat phase, or the wording is in wrong section. Luckily - I don't think this makes a difference, but it does sum up the problems with the rule book.
