Phillipe -
The Allied Logistics card that mentions an extra truck arriving at a "friendly major port". I searched the manual but could find no reference to any differentiation between a port and a major port, and did not see any "major" port references when viewing the region details. In your YouTube video tutorials (which are quite great BTW) at 6:49 in Tutorial 1, you show the card, and then the arrival option is for reinforcement in Alexandria. Why was the truck arrival closer to the front at Mersa Matruh (a friendly port) not an option? I'm guessing it's because Alexandria is a friendly "major port" vs. a friendly "port", but how would one know that? Does Alexandria need some sort of a different reference to show it as a Major vs. a Standard port?
UPDATE: YouTube Video Tutorial1 at 22:14 mentions Alexandria as the "Major Port" for the Allies and Tripoli as the "Major Port" for the Axis, meaning there is only one for each side. Might want to add that to the manual somewhere.
Also, I posted a question earlier in this thread but didn't see a response - are you interested in Game Manual corrections or not? E.g.: On page 19 below Illustration 4.2a, there is a reference to 4.2a and 4.2b, yet page 20 contains an image labelled Illustration 4.22. RECOMMENDED CORRECTION: Re-label Illustration on Page 20 from 4.22 to 4.2b to match the reference on page 19.
I'll quit mentioning Game Manual notes if you are not interested in them....
