Day 9
Not much happens today, mostly positioning. I strike out again with spies, so I'm essentially blind to Oregon's units other than what I can see in the newspaper (at least Tacs, Ints, and Battleships). I'm still comfortably in first place with 330 points, followed by Colombia with 140, Oregon with 100, and Cuba with 90. My economy is really strong, starting the day around 1k/hr for most main resources and a 30k manpower backlog (that is quickly cut in half when I upgrade my heavies).
Diplomacy: Nothing of note
Research: L2 HT research completes a few hours into the day. I start upgrading my naval bomber research, planning to go all the way up to L4 because of Oregon's battleships and the continued threat of invasion from the Caribbean.
Production: once L2 HT research completes I start producing them in all my leveled-up TPs
Construction: I continue building out RCs everywhere. I also build some infrastructure in my slowest provinces between my cores and my armies in the northwest, to speed up future repositioning. I capture a partial L4 TP near my front line with Oregon, repair it, and add a propaganda center, deciding to make it my main front-line production facility for my northwest advance. My Industries at this point are all L4 or L5 and my Local Industries are all L3 or L3 in progress.
Moves: My first major move is to upgrade my heavies that were near Arizona's city stack and then attack, adding mediums to my heavies to eat some of the damage. They made quick work of it, despite most of the units in the stack getting urban terrain bonuses. That basically finishes off Arizona, though I continue to leave buffer provinces between my territory and the AIs. Wyoming has embargoed me and is also in a coalition with Arizona, so might attack me through Arizona's provinces--something I need to prepare for. Colombia has been moving slowly through Central America so I move even more units towards Oregon, with only a few N Cali provinces between us at the start of the day. I notice Oregon is slow in their capture of N Cali provinces and cities, so I rush forward and grab the Steel city and the capital, which only gets me $20k but it's better than nothing, and keeps it out of Oregon's hands. I also grab another supply drop with Goods, Oil, and cash. I stop advancing when I think I've got a good position. Oregon has shown a willingness to surprise attack with Tacs, so I keep my Ints patrolling behind my front lines.
I scout Oregon's units with my fighters and it's looking great: a bunch of L3 infantry, mostly singles; a few L1 TDs; a 10-stack of planes, 8 Tacs and 2 Ints, but they're all still Level 1. No evidence of anything that will stop my tanks. Before day end, I notice that Oregon is also moving units towards my border. I prepare to attack.
Situation at end of Day 9:
