I'm actually playing scenario 141, same setup as above but a bit better for the Allied AI.
20 Inf Battalions, 4 Pnzr Battalions in the amphibious assault, from Briton to Dover
10 Inf Btlns, 1 Pnzr Btln embarked awaiting berths in port
Four Fallschirmjager regiments have dropped north of Folkstone at the start.
The starting air forces are divided into Northern and Western groups, although nothing in the scenario description describes whether they are treated/used separately, or altogether. Presumably the Northern group is based in Norway, the Western in France/Belgium/Netherlands.
42 level bomber groups
10 Stuka groups
Currently Luftwaffe has a 2:1 air superiority
The English Channel is heavily mined on both the Eastern and Western approaches.
Schedules reinforcements include 8 Panzer Divisions over the next three weeks:
