As we all know, "Yours..." is supposed to be about the
Vietnam war - at least that's what Jon has said in interviews.
But what's with the infamous "shining, flying, purple wolfhound"?
1. Agent Purple – like Agent Orange - was a herbicide used by the
U.S. military as part of a Herbicidal Warfare in Vietnam.
Since those herbicides were sprayed from airplanes, the natives
on the ground may have looked up and thought – oh, there’s that

2. The 27th Infantry Regiment is a famous army unit that was
engaged in combat during the Vietnam war. They were/are called
An infantry usually moves by foot. However, during the Vietnam
war, helicopters were used to deploy the US infantry to the battlefield.
The most famous helicopter was the UH-1 (“Huey”).
According to wiki, “UH-1 troop transports were designated by Blue
teams, hence the nickname for troops […] as the Blues. The attack
ships were called Red teams. Purple teams with one or two Blue
slicks dropping off the troops, while a Red attack team provided
protection until the troops could defend themselves."
Hence - a flying, purple wolfhound!
