ROTOR ALIGNMENTS ANP MESSAGE mDICATORS 

3. Discrepancy between the message rotor alignment resulting from decipherment of' the message indicator and the message rotor alignment actually 

required to decipher the message, although the latter was correctly 

derived. Thelliscrepancy involved (a) transposition of letters, (b) 

substitution of a letter alphabetically adjacent to the correct letter, 

{c} substitution of a phonetically similar letter, or (d) errors in 

encipherment. 

4. Failure to tail previously enciphered message. {Reference .AFSAG 1262,
