You can buy a vinyl printout of the board from office max or staples, no idea how it works but I know its been done. Check out the axis and allies Facebook group and ask a question there, someone will definitely get back to you.
Yes, if there is a possible scramble there. Is probably a good idea sometimes.
If you are landing a unit amphibiously, yes it would take the territory unopposed. But you have too clear the Sea Zone first, of course. You fail and the unit stays on board.
wittmann is right, the Italians can’t participate in the German attack so they are bystanders. By rule the German transport should endure one round of combat, then it can retreat if still alive (unless you are playing a friendly game and allow the German player to rethink his move based on the new info).
Our group has had this discussion many times. It seems unrealistic that a country would develop something that is not useful. In one of our games Russia bought a non-disposable tech dice and actually rolled a 6 then rolled on the chart and got “War Bonds” which was cool for them but if you look at the list there are very few that Russia can benefit from. Mostly depends if they are on the offensive. If they are on the defensive then only “War Bonds” and “Increased Factory Production” seem to be worthwhile. “Radar” would also be good but its on a separate chart with tech that would not benefit them. Most would say that Russia should not even consider rolling on tech and I tend to agree unless they are on the offensive and have a massive economy.
