This isn't really a "rule" but…

Because the western Allies can more easily project power and gang up against Japan or Germany, while the axis are too far apart to help each other. Italy is really not much help. They can pile up in Spain and really easily make that a base to attack France, or even do a 2 to 1 in France. Go play it and find out. I did a few times over the years.

@Imperious:

Ok here is the gist of it… you want a unit that can “target” another unit for removal? This is the domain of either armor units ( tank destroyers, SPA, or even heavy artillery)

Infantry would only have it in terms of a commando or special forces unit that goes in and takes out an installation or special tech unit. Use my rule for SPA or allow a unit like a commando unit to choose what it hits if it rolls a one.

Forgot to mention this will be in my D12 games so the hit on a 1 will work.
Elite Guard Inf, SS Inf, Bravo Inf or Black Shirt Inf, Veteran Inf, Commando, and a Marine, A3FR A2 D4 M1 C4 A roll of a 1 can pick target first round only. Can build 1 per turn only.

I think 2 a turn may be to strong. I can put a token under a inf piece or stack showing how many get the special shot if you can build 2 a turn but only 1 gets the special shot.

Here is an interesting bit of historical trivia. The US 8th Air Force actually had bases in the Ukraine for a short time. From June to September 1944, the 8th Air Force started a shuttle run of bombers that would take off from England and Italy, bomb targets in Germany then fly on to 3 bases in the Ukraine, Piryatin, Mirgorod and Poltava. The reasoning was mainly to show solidarity with the Russians and to hit Germany from an unexpected quarter.
The mission was called “Operation Frantic”. I don’t think it was much of a success. One reason is that the Luftwaffe bomber arm was still fairly strong in the East. Some Luftwaffe planes saw the American bombers heading into Russia. Then when a shot up P-51 crashed in Poland, it had documents on the Russian bases. Luftwaffe command was notified and they send Fliegerkorps IV, nearly 350 He 111s, to pound those bases while the B-17s were lined up in neat rows due to lack of space. It was the 8th Air Force’s costliest single operation of the war.
I didn’t even know about this until I read it in World War II magazine.

I like it, but I think 10 turns is too late, as one side or the other will have achieved a clear victory by that point (even if the game isn’t over). I think mid-to-late game, maybe around turn 7 would be a better time to introduce the bomb. I also think that the bomb should cost 40 IPCs, must be carried in a strategic bomber, and can be shot down. Finally, I think the bomb should do max damage to all facilities, and if used to attack units, it should automatically wipe all of them out. The bombs should only be producible in a major IC.

I added various links and made some changes to the first three parts of the rules, technology, and units.

yeah smaller territories with the World at War variant

starting with OOB you actually want to WEAKEN SBR rules
you can make German bleed in a way thats too powerful for both gameplay balance and realism

hitting things during production is a great idea
it doesn’t make sense to be able to destroy IPC at an unused IC
but I wouldn’t make it actual units but remain as IPCs

its not easy to make a nice rule for OOB though
the income and production is all messed up by the USSR,Germany,UK,Japan,US play order
