I assume by what you’re saying that I can go backwards in the game and relive the various moves.
Nope. You could try setting up a game with you playing all powers, and try to recreate the situation though.
I wasn’t trying to eliminate them, but in the videos, the swooshes appeared to be 1/4" or so and on my screen they were like 3/4 of an inch. They pretty much covered the width of Japan making it hard to see what else I had left. No biggy.
They used to have the lines connected to the UI, with individual lines for each unit (not merely unit type), which resulted in literally uncontrollable situations when there were too many lines.
Use those starting AA guns in the US. They’re just sitting there doing nothing. Use them. Maybe you had the UK take France and the UK has a few units left in France. Have the US go drop another 10 in France behind them, and make one of those units an AA gun.
A warning though: Check to see if Germany can re-take France. If they can take it, how many units will they likely have left in France after the battle? If it’s low enough that the Allies can re-take it the next turn, then by all means throw everything in. It’s just a large trade. You’re exchanging UK and US units for German units and that wears Germany down. If Germany has enough where they can take it and then stack it so it can’t be retaken then be cautious and just drop a minimal number in.
For NW Europe, this is likely just 1 transport. For France, it’s more because it’s a 6 IPC value territory in the situation of a strafe. Sometimes Germany will have a lot that they can bring at France, but if they bring everything then it leaves them too weak elsewhere. For example, if they bring 25 infantry and some tanks to France to take it hard, then that would leave them too weak in Germany.
In that situation bring 3 transports to France to leave about 4 or 5 there. It’s too few for them to do a strafe because they don’t want to lose the income from France. It’s too many for a light trade, so you’re still getting your goal of a heavier trade.
You have to read the situation in Europe though. Sometimes it may even be worth it to have a negative net trade with Germany if it’s early game and Germany is pushing at Russia hard. It will divert units away from the eastern front.
Subs are by far the most cost efficient naval attack purchase. Surprisingly, they do okay in defense as well since hit points are so important. Japan should only buy subs if usa purchases pacific naval units round one. Since subs have more attack than defense, the usual dynamic is that two fleets are 3 spaces apart. The stronger navy will try to move to two spaces, either through enough defensive strength or with destroyer blockers. The other side has the choice of building up defense, countering similarly with blockers, or retreating.
3 transports, 3 infantry is an all around flexible and powerful round 1 purchase. If UK attacks japan sz37, this strongly suggests KJF and a buy of 1 trans, 3 sub 1 inf might be more appropriate.
