I did a quick google to check it out. Mogadishu defintely appeared, and Entebbe as well. I'm kind of rushed now, so I put Entebbe in the post without much detailed checking. Entebbe stuck in my mind for some reason.
I'm not exactly sure what the Entebbe connection is, though. The Google hits were related with Entebbe and Badder-Meinoff.

Nice background Info here: Specialoperations.com....Germany Grenzschutzgruppe 9 (GSG-9)
excerpt..
Born out of history and tragedy, GSG-9 was created right after the 1972 Munich Olympic massacre, to combat the ever growing terrorism. Created within the Federal Border Police (Bundesgrenzshutz), and not the military, to avoid the impression of a new SS, the creation of the unit was give the go-ahead on September 8, 1972. Placed in command was Ulrich Wegener. An expert on counter terrorism, he modeled the GSG-9 after the Israeli Sayeret Mat'kal. It was even rumored that Wegener took part in the Israeli rescue in Entebbe.

Both. GSG9 commander Ulrich Wegener was along with the Israelis at Entebbe, where he was slightly bayonetted by a Ugandan soldier. Who was somewhat more effectively dissuaded from further such activity by Wegener, who had arranged the supply of silenced American Ingram M10 submachineguns and other specialized equipment for the Israelis, including possibly a Mercedes limosine identical to Idi Amin's.
GSG-9 made its reputation on the night of October 17, 1977, when they stormed a hi-jacked Lufthansa plane in Mogadishu, Somalia, rescuing all 90 hostages and killing three of the four hijackers.
