As I was cutting out my Hungarian units for Festung Budapest
I noticed that the vehicle crew have factors of 1-2-6 while the ones from Armies of Oblivion
have factors of 1-2-7. According to D5.1:
Inherent crews of unarmored vehicles take MC with a Morale Level equal to that crew nationality's best unbroken 1st Line Infantry.
Accordingly, they should have factors of 1-2-7. Is this a misprint?
There's no direct relationship between the morale level of an inherent crew of an AFV and the morale level of the crew counter that represents it when it takes counter form outside the vehicle.
The full quote from D5.1 is: "While inside an AFV, the crew checks morale with a Morale Level equal to that of its nationality's best unbroken elite Infantry MMC; Inherent crews of unarmored vehicles take MC with a Morale Level equal to that crew nationality's best unbroken 1st Line Infantry"
Take the Germans as an example. When you check morale against the inherent crew of a German AFV it is 8 (equal to best unbroken elite infantry MMC). It could even be 9 for a Tiger tank (per the special note on the back of the counter). But, in either case, when it takes counter form outside the AFV it is a represented by a 1-2-7 crew counter.
Unarmored vehicles check morale with the morale of the best 1st line infantry. So for the Germans that would be a 7. But remember that most unarmored vehicles, like trucks, cannot generate a crew counter at all. They usually have a crew survival number in lower case like "cs 5" which means you only roll survival for passengers and riders but no crew counter can be generated.
