Do you use some AI modifications? I've never seen this happen before - a successful invasion of Britain by AI controlled Germany?! Just wow...
I have done nothing to the German AI. This is Arma v1.2's AI in action. Ever since I patched to this version, I have noticed a very impressive boost in the AI's use of amphibious attacks. An AI sealion also seems to depend on a few factors. First, the number of units positioned in the UK. Second, the amount of transports that the German navy possesses. This is actually the second time in a row that I have seen an AI sealion. The first time was when playing as a Nazi Sweden. On that occasion, the Germans managed to completely conquer the UK, only to lose it once the Americans joined the war and landed 300,000 men to liberate the island. The US AI is also improved, and I should see them do things like invade Italy and France.
Soviet technological progress at the beginning of 1941. We are starting to catch up in the areas of air and land warfare doctrine. The USSR has also gained the ability to construct infantry divisions equipped with armoured personnel carriers.
The US begins to assert itself on the world stage, taking control of Greenland and Iceland from the British, and beginning an oil embargo against the Japanese empire.
On March the 2nd, the Axis nations invade Yugoslavia from all sides. Bulgaria even joins the war a day later.
The Italians are embarrassed yet again when Yugoslav troops occupy Venice.
When the snow melts in the UK, Churchill orders his now sizeable force to crush the German troops in England once and for all, and liberate the people of the British isles from German occupation. The Germans, whose navy cannot transport reinforcements to the area due to the naval supremacy of the Royal Navy, are powerless to stop the British onslaught.
The new armoured corps are almost finished forming up, now only waiting for their accompanying mechanized infantry divisions to complete training.
On April 5th, the British force the surrender of the last German troops in england, and Churchill proudly announces the Liberation of southern Britain. However, northern Ireland is still under German control.
In North Africa, the British are beginning to break Mussolini's hold on Libya. Also note the failed landing in Homs, where 30,000 troops including a division of tanks were forced to surrender to Italian troops.
The Kingdom of Yugoslavia falls to the axis nations, just as Italy declares war on Greece. The greeks are forced to surrender about 2 weeks later.
Stalin orders the expansion of the long neglected Soviet navy, with battleships, light aircraft carriers, and escorting destroyer flotillas being constructed.
