I have to echo the posts of others here… an Allied IC is a bad move.
US IC somewhere in the world? Why? No better place for the US to stage against Germany than direct from Eastern US. Versus Japan? Not worth it. Why build an IC where you cna only build 2 units AND it is located away from the coast where you could later build land AND naval forces to invade Japan.
UK? Again why. Best possible position to attack Germany, with no risk of Germany attacking your existing facility with a ground based strike. India? Unless you do EVERYTHING possible as the allies to defend it, Japan is going to take it, period. And if UK pours that many resources into India, Germany is going to pounce on Russia big-time.
Russia? WORST possible move in the game. Sure, build a Yakut IC, defended by your consilidated INF and tank from the Eastern territories. That is 5 less INF that Germany has to chew through the round after Russia buys it, and perhaps more later as Russia places some units at the new IC to defend against recurrent strikes by Japan… not to mention the free SRB run Japan would get to destroy an addiitional 1-2 Russian INF’s per round. Not to mention that, no matter what Russia does, Japan WILL take that IC in Yakut, and then start building westerward bound forces to use against Russia.
Germany building an IC is suicide, period; unless the Axis is already so heavilly dominating the game that it is effecftively over anyway.
As Japan? Well, once my tranny’s are built up and forces are flowing in a torrent toward Russia I MIGHT build a mainland IC. But probably not. I’d rather just keep building tranny’s and filling them up creating an unstoppable wave of forces heading toward Moscow. As far as supporting Africa as Japan: I’ll mess with Africa after I take Russia. I can build in Moscow then and send tanks to Africa to seize it. And by using tranny’s as Japan, as soon as Russia falls, my forces turn across the Pacific and strike at the US on multiple fronts in force… no delay to re-tool from land forces in Asia to naval forces to cross the Pacific.
