German composition for the Battle of France:
Germany had mobilised 4,200,000 men of the
Heer, 1,000,000 of the
Luftwaffe, 180,000 of the
Kriegsmarine, and 100,000 of the
Waffen-SS. When consideration is made for those in Poland, Denmark and Norway, the Army had 3,000,000 men available for the offensive on 10 May 1940.
[57] These manpower reserves were formed into 157 divisions. Of these,
135 were earmarked for the offensive, including 42 reserve divisions.

Communications
The
Panzers all had radios that allowed voice communication with other units. This enabled German armour to respond rapidly to a constantly changing battlefield situation. It allowed for last-minute changes in tactics and improvisations to be formed far more quickly than the enemy could. Some commanders regarded the ability to communicate to be the primary method of combat.
[66] Radio drills were even considered more important than firing accurately.
[66] Communication allowed German armour to coordinate their formations,
bringing them together for a mass firepower effect in the attack or defence.
Luftwaffe
One of the German strengths was the
Luftwaffe. It divided its forces into two groups. In total, 1,815 combat, 487 transport and 50 glider aircraft were deployed to support Army Group B, while a further 3,286 combat aircraft were deployed to support Army Groups A and C.
[72] In the first year of the war, the
Luftwaffe was the best-trained, modern and experienced air force in the world.[

Anti-aircraft defences
It is generally supposed that the Germans also had a major advantage in anti-aircraft guns, or
Flak. In reality, the generally cited figure of 2,600
88 mm (3.46 in) heavy
Flak guns and 6,700
37 mm (1.46 in) and
20 mm (0.79 in) light
Flak seems to refer to the German armed forces total inventory, including the anti-aircraft defences of Germany's cities and ports and the equipment of training units.
