Kaserne, Pirmasens, 1966-68
German construction worker slaps on mortar to close off
windows (including the stairwell window on the right) on
the third floor of Bldg 4616. Appears that air conditioning
vents have been added. Could be that it involved a "secure
area" for commo/crypto gear. An interesting observation
is that a/c units were very unusual in Germany! Anybody
have any idea of what was being done here?
