The Delta Force dog that cornered the leader of ISIS before his death has become America’s favorite animal. President Trump declassified a photo of the dog, but his name remains classified, leaving Americans to make up their own. Some have called the K-9 “Sgt. Classy” and “Rambone,” while the New York Post front page calls it “Zero Bark Thirty," a play on the title of the film about the famous raid of Osama bin Laden's compound. The dog is a Belgian Malinois, one of the smartest breeds.
