(Lance Cpl. Jamal Norris/Marine Corps) In February junior Marines looking for promotion to corporal or sergeant will see a new, more robust promotion system, designed to reduce the importance of any one event and give commands greater input on noncommissioned officer promotion. The new junior enlisted performance evaluation system, or JEPES, will replace the old pros/cons method and will be made up of three objective scores ― called war fighting, physical toughness and mental agility ― combined with a more subjective score provided by a Marine’s command, called command input.
