Up to the second half of 1940 the panzer division was the only true mecanized unit in existence outside the USSR, the French units were totally unsuited for mechanized warfare and the British were still forming. going by memory: A 1940 Panzer division two to four tank batallions, 3 infantry batallions, an artillery regiment, recon batallion, AT batallion, Engineer batallion, lots of support troops, it was capable of sustained offensive operations though it was a bit short in inantry for defensive roles. British Amoured Division: two tank regiments and a brigade sized support group of infantry and artillery, it the desert campaign the unit proved to be capable of sustained offensive ops though 1st Armoured in France failed to achieve anything significant. British Army Tank Brigade was an Infantry tank support unit with no organic infantry or artillery to speak of. French DCR two tank regiments and very little else, same limitation as the British Army Tank Brigade. French DLM was a light division geared for reconnaisance, a role where they failed miserably though their heavier tanks were a tough nut to crack for the Panzers. The TOE is pretty interesting 160 tanks (80 Somua 35 and 80 Hotckiss 35) and around 100 Panhard 178 armoured cars (though that number looks high) a sizeable infantry complement including 3 companies if engineers and one of bridging engineers but very little arty and .... an anachronistic detachment of carrier pigeons ! The Kursk era Panzer division was not terribly different from it's1940 predecessor, two batalion of tanks 4 of infantry (6 in the SS), an artillery regiment (significantly stronger than the 1940 one), recon batallion, AT batallion, Engineer batallion, lots of support troops.
