What is a METL and what is a T and EO?
A METL is a mission-essential task list, the tasks a unit must be able to perform to accomplish what it was designed to do. A training and evaluation outline, or T and EO, is the standard for a specific task: the conditions, the standard, and the performance measures a leader uses to evaluate it. The T and EO is the starting point for any honest proficiency assessment.
