Nationality issues

[yardslave]

I have a question concerning nationality. I played a scenario that included English and American troops. It seemed like the nationalities were not able to attack a single unit in concert.

I had to attack with one nationality then with the other.

QUESTION: Can the two nationalities attack a single unit by combining the strength of all or do the nationalities have to attack separate from each other on a single unit.

Different countries must attack separately. Quick rule of thumb is if the units can stack together, they can attack together.
