Tank Companies
Given the ever changing nature of the armoured forces of World War Two, it can only ever be possible to capture a snapshot. To partially complement the Armoured Infantry Companies section, I have also tried to put something together regarding the tank formations they fought alongside.

Notes
British - during Normandy, the Squadron organisation detailed here was changed notably. It had been planned that one tank in each of the five Troops would be upgraded to the Sherman Firefly. However, insufficient numbers were available, and instead only four could be issued per Squadron. As a result, Squadrons realigned themselves, deleting the fifth Troop, adding one Firefly to each remaining Troop and removing one tank from HQ (either a Cruiser or a CS tank). As more Fireflies became available, some units moved to the original idea of five Troops, each with a Firefly, others still settled on two Fireflies and two Cruisers per Troop, still with four Troops per Squadron. The description is therefore nothing much more than a glimpse of the paper ideal. Likewise, the issue of rifles, Stens and pistols is not given, so these are purely my estimates. Taken from II/151/3, dated 30th November 1943.
American - previously culled together from descriptions on both http://www.752ndtank.com/TOE.html and the ever expanding www.militarytablesoforganisation.com the description is now taken from the TO&E 17-27 of September 1943, plus changes of June 1944.
Red Army - this is copied from the above mentioned book obtained from www.helion.co.uk and also available from the Nafziger Collection in the US.
The Company has several interesting points, not least the proliferation of officers and the almost total absence of any service personnel. The author notes it was common for the Deputy Commander and Technical Officer to scavenge their own vehicle as none was officially provided. As there is no indication of personal weapons I have simply opted for the most likely options, namely a pistol or PPSh submachine gun.
German - donated by Piet Duits, taken from the 1st April 1944 organisation KStN 1177(f.G.). This was not quite the final variant of the Panzer IV or Panther Company. The 'dismounted' 4th Platoon was deleted, along with the fifth tank in each Platoon during the latter part of 1944, as Panzer losses swelled.
