Although I’ve given up on getting these files (for reasons that have already been mentioned) I will post this information in the hope that someone else will succeed.
At the US national archives, in the NSA transfer group TR-0457-2016-0017, box 45, folder 3953 there is a file titled ‘KOMMANDEUR DER NACHRICHTEN AUFKLARUNG 5, 1944 (S-013,494)’.
It is possible that this file contains the missing NAASt5 reports. Maybe someone can get hold of this file and solve the mystery.

Information on this year's International Conference on Historical Cryptology:
The International Conference on Historical Cryptology (HistoCrypt) is an annual conference on historical cryptology. The 2019 edition will be held from June 23-26, 2019 in the Mundaneum, Mons, Belgium.
HistoCrypt addresses all aspects of historical cryptography and cryptanalysis. The conference's subjects include, but are not limited to:
the use of cryptography in military, diplomacy, business, and other areas
analysis of historical ciphers with the help of modern computerized methods
unsolved historical cryptograms, including the Voynich Manuscript
the Enigma and other encryption machines
the history of modern (computer-based) cryptography
linguistic aspects of cryptography
the influence of cryptography on the course of history
teaching and promoting cryptography in schools, universities, and the public
Participation in the conference is mandatory for at least one author of each accepted paper.
Submissions from those who are new to the field, particularly students, are very welcome.
We are looking forward to seeing you in Mons, Belgium

1). ‘A German perspective on allied deception operations in the Second World War’ by Klaus‐Jürgen Müller. (excellent analysis of the problems of Anglo WWII historiography)

Impressive analysis of the Asia Minor campaign of 1919-1922 (in Greek):
I’ve always been interested in the Asia Minor campaign but unfortunately the books I’ve read so far tended to lack an in depth analysis of why the Greek forces failed to defeat the weakened Kemalist army.
The essays posted at the aforementioned site clearly point out the underlying problems of the Greek armed forces: the lack of professionalism of the officer corps, the rigid planning at the operational and strategic level and the lack of support between infantry, artillery and cavalry.

In The American M-209 cipher machine I added info on the unit NAASt 7 and the section:
Invasion of Sicily
In July 1943 US and British troops invaded the island of Sicily and after more than a month of fighting defeated the Axis forces and captured the island. However the German forces were able to avoid a total defeat by retreating in an orderly fashion through the Strait of Messina.
It seems that during the fighting in Sicily the Germans managed to capture a valid keylist of an M-209 network and thus read current US military traffic (14).
The war diary of Inspectorate 7/VI says that in July ’43 the captured material allowed the continuous decryption of the traffic with indicator ‘ID’ and the results were communicated to NAAst 7.
The report of August ’43 says that messages of the ‘ID’ network could be decoded till mid month and after that it was still possible to find several cases of indicator reuse and thus solve the traffic of those days cryptanalytically.
