Prizren political art 3: NATO vehicles and other property have an arrow-like symbol and the name, "NATO", printed on them, similar to this logo.

There are sites where members or supporters of the Kosovo Liberation Army (KLA) (Ushtria Clirimtare e Kosoves (UCK)), have written "UCK" and "NATO", signifying their alliance, so it is possible that this is a tag for an ally who, obviously, would never write a tag themselves.

The solitary marker, on a burned-out building, however, suggests that it may be, rather, branding by an opponent of the NATO bombing, indelibly tying NATO's intervention with the deaths of civilians and the destruction of communities.
