Army Security Ageny Europe (ASAE) SIT (Special Identification Techniques) Office

The Headquarters was in the Abrams (IG Farben) Building and the troop billets was in Gutleaute Kaserne which was only a few blocks from the main Haupt Bahnhof (main train station) in downtown Frankfurt.

ASA Headquarters Europe was dissolved in 1972 during the European Field Station closures and mission consolidation to FS Augsburg.

During the period when Headquarters USASA Europe was in Frankfurt, Germany (50s, 60s early 70s until Field Station Augsburg became operational) there was a SIT oversight office in the headquarters as part of the staff. Apparently there was a maintenance and inspection team operating out of USASAE tasked with assisting the sites and helping to maintain optimum maintenance and operational levels.

We have gotten a good preliminary story from one of the MOS 286 (Radio Maintenqance) members of the team, Ron Knief, about visiting Lubeck, Gutleute Kaserne and a few other odds and ends. Ron's memory is just below.. He also sent in a bit about Sinop and several excellent photos.

I ran across your site this evening and thought I would touch bases with you especially on the DF sites that were in the North of Germany. I suspect that you have only covered more recent sites and haven't reached "back in history" to some of those that I serviced.

I was assigned to HQ USASE and stationed at Gutleut Kaserne (shared with the 709th Military Police Battalion), which was five blocks, or so behind the main railway station at the head of, what was then, one of the greatest duty towns in the World, Frankfurt. The Kaserne was originally built for the Prussian cavalry in the last century and was used to interrogate downed U.S. bomber crews in the Second World War. I worked out of the concrete building in the park to the right of the I.G. Farben bldg., which the Germans called Hoch Haus (we said whore house). The I.G. Farben Bldg. was where USASAE and I believe several other HQs (7th Army?) were located.

In late 1959, early 1960 I was assigned to a DF team, which was tasked with keeping all the DF sites in Europe in tune. That included the R-390 receivers and all the ancillary equipment that went into a DF site. I went to Luebeck and Helmstedt, which were located in the old British zone. We wore civilian clothes (something to do with the Four Powers Agreements) and drove a deuce and a half with our equipment in it and a jeep that carried the other two of the four-man team. The German girls in the British zones, by and large, had seen little or nothing of Americans and we were welcomed everywhere. When we drove into downtown Luebeck (picture four guys wearing civvies driving two U.S. military vehicles) we came to a major intersection in the center of the city and a German cop in a full length white leather coat blew his whistle stopping traffic in all four directions and bowing low waved us through with a smile. I thought "Hey I like this area!" The GIs at that time hadn't ruined the relations with the Germans up there! I loved Luebeck and nearly every night I spent my time chasing the local gals around two large ships converted to great dance clubs with night clubs on different decks. You could jump on a canvas slide to take you from higher to lower decks. It was a great place! Both ships were anchored in the river that branched around the center of the old town. Helmstedt was a bit different and more remote from larger towns but we managed to visit Wolfsburg and toured the enormous Volkswagen factory.

I also went to Straubing and Giebelstadt in the south of Germany and worked on those sites, both of which if memory serves me right, were on U.S. Air Force bases. I sampled every Bavarian beer I came across. German beer is the only beer that I was ever able to drink with breakfast.

Cheers! Ron Knief
