secret communications systems for the Luftwaffe. Air-to-air
communications, which were mostly by voice, employed simple
codewords to disguise unit names, much as American pilots referred to

largest subdivision was Luftnachrichten ("Air Intelligence") Regiment 351,

detailed information on the heavy bombers. Smaller regiments covered
other theaters. Luftnachrichten Battalion 350, with 800 men, served as
the Luftwaffe center for basic cryptanalysis and traffic analysis, as well
