Koala Soldiers
During the Vietnam War, conscripted Australian soldiers were derisively called "Koala soldiers" by regular army personnel. The rationale behind this name was that they were 'not to be exported or shot at.' It is now commonplace within the civilian population to use this nickname to refer to any deployment of troops with restricted rules of engagement.
Qantas airlines used a Koala who continually complains about the airline's reliability in a series of television commercials.
The Koala is the official mascot of Columbia College, a women-only college in Columbia, South Carolina.
The Koala is a student newspaper at the University of California, San Diego.
