Hello,

for the training of (German) reservists I am looking for training documents - gladly also in English - for vehicle recognition. Eastern bloc AND Western weapon systems.

On the Bundeswehr intranet I have only found a PDF for ISAF. With armoured vehicles that occur in Afghanistan. So it is very limited...

Is there anything from the USA Army or the British on the internet as a PDF?

Yes, I know Wikipedia... what I am looking for is a simple manual. 
e.g. T** = 5 road wheels and **mm gun; T** = 6 road wheels and **mm gun.

Thanks!

Here are some 'cards' on Russian equipment

Put "military vehicle identification cards" in your favorite search engine. Mostly historical information, but there was at least one company making cards of modern stuff. Hope it helps!

The US Army FM 3-23.24 could be helpful, along with GTA 17-2-13.

A friend of mine used to make a a small pocket notebook with all these stats.
