The progress of my old NSA freedom of information act cases or alternatively ήμουν νιος και γέρασα…

So far my remaining cases with the NSA FOIA office can be broken into two groups. One concerns requests I made in 2015 and these seem to be progressing slowly but I expect I will get responses this year.

The problem is that my old cases from 2012 seem to be stuck in time. Back then I requested several TICOM reports and even agreed to pay for two large files (~500 pages).

Since then I’ve been told that these cases are being processed, then they were in the review queue, then final review etc.

Update

I’ve added information from TICOM report I-26 ‘Interrogation of Oblt. Schubert (OKH/Chef HNW/Gen.d.NA) on Russian Military and Agents’ systems at OKM Signals School, Flensburg on 17 June 1945’ in the essay Soviet partisan codes and KONA 6.
