USMLM Annual Histories

Interesting that USMLM histories are publicly available, but BRIXMIS histories are not.
Of course, these once classified – SECRET –  annual reports are now publicly available – unclassified – so may have been pre-scrubbed precisely because they were made public. However, a quick glance at the 1988 history seems to suggest that they are pretty comprehensive and, as far as can be seen, only the SECRET header classification has been redacted.
Maybe, they contain different – ie. less sensitive – material that allows disclosure, versus non-disclosure. However, again, a quick glance at 1988 shows distributions, names, targets, activities, photographs, amongst most other things one would expect from this originally secret document.
Thus, it is curious for at least two reasons: first, given the US propensity for ‘secrecy’ one might not have reasonably be expected to have access to such material at all; second, it rather begs the question why the British equivalents are not available given that the three Military Missions did incredibly similar (co-ordinated even) things.
