Not sure what it has to do with anything, but I ran across this astonishing video of a Chilean military parade in 1992, complete with a rousing rendition of Preussens Gloria. You may not know the title, but you’ll recognize the music as well as a few other things in the video. Again, this was in 1992.

Lest you think this has changed with the demise of the dictatorship, this is the 2012 Grand Parade in Santiago, longer but with the same choreography and costuming:
