TIME OFFENSIVE is a military strategy in which an attacking force uses the element of surprise to gain an advantage over the defending force. The term is derived from the Latin phrase 'tempus edax rerum, ' which translates to 'time devours all things.' TET is an acronym for the phrase, which stands for 'Tempus Edax Rerum.' This strategy has been used throughout history, most notably in World War II, when the German Blitzkrieg was a prime example of a time offensive.
