Sometimes we will use British bomber(s) to hit Northern Italy IC.
US bombers based in London often will hit Normandy, S France and France ICs. Sometimes will hit W Germany if German player doesn’t have too many fighters to intercept. Also will hit Germany if Allies control Norway or Novgorod for bombers to land.
If US Navy is doing well in the Pacific, US usually takes Iwo Jima and lands bombers there to pound Japan’s facilities. Often escorted by Carrier planes.
Strangely enough, don’t usually do a lot of SBRs with Axis bombers.
