From The General 18/3

D-DAY:

Q: Exactly how do rules 16.7 and 16.8 limit my ability to land units
(including paratroops) on the continent? 

A: This question has been repeated so many times, in so many forms, that
we have restated the rule and changed it somewhat in the latest D-DAY rules
folder. The revised rule 16.7 is given below and is an official rules
change. There is no longer a 16.8. 

16.7 Important: Each unit that invades or lands by sea is supplied that
turn, and counts against the capacity of the hex where it lands. If the
hex does not have enough capacity to supply the unit, the unit cannot
land at that hex. Thus, the number of units that can land at a hex
equals its capacity, minus the on-map units it is supplying. 

16.71 The Allied player must supply as many of his units as possible. He
cannot choose to leave units unsupplied in order to increase the number
of units he can bring ashore. 

16.72 Airborne units are automatically supplied on turns when they air
drop. They do not subtract from supply capacity until the next turn. 

Q: OK, how does the revised rule 16.7 limit my ability to bring units
(including paratroops) onto the continent? 

A: With regards to units landing (or invading) by sea, both supply and
landing count against supply capacity. Thus, the number of units that can
land at a port (or other landing hex) is equal to its un-used supply
capacity. Paratroops can land free of supply restrictions - they can still
drop even if there is no unused supply on the continent. 

Q: Can I choose to leave some of my units out of supply so I have extra
unused supply capacity that I can use to land more troops? 

A: No! Rule 16.71 expressly forbids this practice; you must supply what
you can, and only the excess capacity can be used to land units. 

Q: How is this revision different from the original version? 

A: It clarifies the point that events during the Allied turn have no
effect on their ability to land units that turn - regardless of what units
are lost and what supply paths are opened, the supply determination at the
beginning of the turn defines what can land. It also clarifies two points:
paratroops who drop do not affect other unit's ability to land by sea,
and supply/landing restrictions apply to each city individually. 

Q: An Allied-controlled port that was not invaded and that does not
contain a HQ unit can supply only the units in its hex (rule 16.535). If
such a port has unused supply capacity, can this unused supply capacity be
used to land units? 

A: Yes. Unused supply capacity can be used to land units even if the
supply cannot be used inland.
