Jag Panzer were formed in 1981 in Colorado, by Harry Conklin, Mark Briody, John Tetley, and Rick Hilyard.

They were originally called Tyrant, but when California based record labels became interested, they realized that there already was a band called Tyrant in California.
Seeking inspiration from a book of World War II German armour in the library, they decided to rename themselves after a slightly easier-to-pronounce version of the Jagdpanzer tank.
