What unit did Spy Rudolf Roessler served with in World War I?

Hi,

late reply, but hopefully not too late.
First of all, it must have been WW II.
Rudolf Roessler worked for the spy ring of Alexander Rado and Alexander Fotee in Switzerland, who worked for the soviet military intelligence service (GRU).

Kind regards

Roesler, like Hitler, was a WW1 veteran but I don't know in what unit. http://de.wikipedia.org/wiki/Rudolf_Roessler

During WW2 he was in Switzerland.
