This topic came up in a recent game, and it’s obvious to me what the correct answer is, but for the sake of completeness I’m asking it here.
The wording “and/or” in the NOs was interpreted by some to mean that both countries listed on both sides of the “and/or” must be owned to achieve the NO.
For instance in the Italian NO of “Axis control of at least three out of the following: Egypt, Trans-Jordan, France and/or Gibraltar”, two of the three countries under Axis control from that list must be France and Gibraltar since the “and/or” is between them.  For this particular example, my interpretation is that any of the three countries under Axis control will suffice to achieve that particular NO.

For #1, does that mean that attacking infantry will hit on a 2 or less and defending infantry will hit on a 1???
Or is it that attacking infantry now have an attack power of 2 and it doesn’t affect defending infantry???
Or, does it mean that infantry attacking hit on a 2 and defend on a 1???
If it’s the first, than what if both sides have the same technology?

For #3, do the planes fly to an area and automatically kill 1 unit and then are removed, or does it just mean that they can now fly to areas to attack without having to have a safe place to return to???
