German Unit Organization/Abbreviation Question

[SGTGunn]

Hi,

Does anyone know of a good online source for Heer unit abbreviations?

For example, in the US Army the 1st platoon of A Company of the 2nd Battalion of the 27th Armored Regiment would be written 1/A/2-37 AR. I'm trying to figure out what the Heer equivalent of something similar would look like.

Also did German tanks use "bumper numbers" similar to the US practice i.e. US Army tanks in 1st platoon, A Company would be A11, A12, A13 & A14 (in the newer system)?

Thanks,

Adrian
