I typically do 1 fig, 2 inf in the UK and an MIC for Egypt on UK1. I do not do Taranto usually, so the Scotland fighters (one gets placed with the bid pretty much all the time) wind up in the UK. One fighter usually goes off with the sea zone 109 DD and the strat bomber to kill German subs in sea zone 106, but I’m still left with four fighters in the UK plus the augmented infantry force. The four fighters are enough to dissuade unescorted strat bombing, and Germany usually does not have fighters positioned for escorted strat bombing on G2.
This approach puts Italy in the position of having to spend money to try to save its fleet, which it cannot do for more than a three turns. During this time, it is spending money on fleet and not on European defenses or fast movers to help Germany in Russia.
Once the UK kills the Italian fleet, Italian income sinks rapidly due to convoy disruption. If Italy doesn’t try to keep its fleet alive, it loses income sooner and can’t contribute.
Either way, Italy is very weak.
This secures the Med, allowing the UK to focus on the Middle East starting about turn 4 and shipping fighters to Moscow on turn three. It keeps Italy from helping Germany significantly with defense or offense.
Starting about turn 3, I try to add one infantry per turn on average to the UK to build for the eventual possibility of a late Sea Lion attempt.
