This is called a GroΓer Zapfenstreich, the people on the second picture are Joachim Gauck and Ursula von der Leyen, at the time when Gauck was president and von der Leyen defense minister. It can take place on different occasions but the most common is to honor the president, now at Schloss Bellevue in Berlin. The second and third pictures were taken when Gauck left office in 2017 while the first one comes from another GroΓer Zapfenstreich, in Dresden.
