A homemade video televised Thursday shows German army officers giving the Hitler salute, talking about killing Jews and making anti-Semitic and anti-foreigner comments.
Eight members of Germany's 571st Mountain Infantry battalion appear in the video -- the same battalion that produced a homemade video discovered three months ago of soldiers pretending to carry out rapes and killings in Bosnia.
The latest videotape, an apparent prank, is almost certain to damage further the image of the German army, which only recently started assuming a more active international role after World War II.
In Bonn, Defense Minister Volker Ruehe ordered an investigation into the latest video, likely made in 1994 or 1995.
The SAT 1 television network, which alerted the Defense Ministry about the tape, aired excerpts Thursday night. The network refused to reveal how it obtained the video.
The excerpts showed a helmeted soldier giving the Hitler salute. Another soldier, in close-up, identifies himself as a Jew and says, "I take the German people's money."
The final excerpt shows two soldiers pretending to be neo-Nazis beating someone up.
