K-Town is a simplified
name, used by the US troops, for Kaiserslautern, which is a city in
south-west
Germany where many, many US forces are stationed.
You might know it from
TV reports about the war in iraq. The
famous Landstuhl US military hospital and the US airbase in Ramstein, the largest US airbase
outside the US, are located at K-Town.
Unfortunately, Kaiserslautern seems to be too complicated for foreign tounges, so they say K-Town.
