In the Museum of Military History Vienna (http://www.hgm.at/) different documents from this timespan are exhibited. Most of them are in German and in Hungarian. It is explained that there is a difference between the “normal” Language for orders (written) or communication and the “commando” language. Only Hungarian and German were allowed as “commando” language. “Normal” Language also included Italian. An interesting exhibit is field manual printed on a piece of cloth. It includes instructions how to care for the gun or react on orders. One side of the manual is in German and the other is in Hungarian.
