EAGER LION (EL) was first executed in 2011 as a bilateral exercise with a focus on irregular warfare and grew to a multilateral exercise for the 2012-2015 iterations. EL began alternating bilateral (even years) and multilateral (odd years) from 2016-2019. EL24 is the 11th iteration of the exercise; the next EL will be in 2026. The exercise was designed to promote cooperation and interoperability, build functional capacity, enhance readiness, conduct interagency coordination and integration, support civil authority including critical national infrastructure protection, cyber defense, maritime security, operations in a chemically contaminated environment, and integrated logistics. Following the COVID-19 pandemic (which resulted in the cancelation of EL 2021) EL became a biennial, multilateral event executed only on even years, alternating with Exercise Bright Star in Egypt on odd years. EL is one of the largest and most complex USCENTCOM exercises maintaining the central theme of defense against hybrid threats and non-state actors.
