Dozens of exercises, four countries, and a busy and proactive summer just about summarize Resolute Sentinel 22. The exercises began in Guatemala in March 2022, moved to Honduras and El Salvador, and will end in Belize in August, providing joint training and improving readiness of United States and partner nations’ civil engineers, medical professionals, and support personnel through humanitarian assistance activities.
“We need to increase our level of training and the best way to do that is through our allies like the United States,” said Salvadoran Army Major Carlos Díaz, head of the medical division at the Central Military Hospital in San Salvador. “We recognize the U.S. doctors, medics, and nurses have a lot of experiences. We arranged some exchanges in trauma, doing rounds and learning from them and also to see how to use our resources.”

Resolute Sentinel is a new U.S. Air Forces Southern/12th Air Force-led U.S. Southern Command (SOUTHCOM) exercise that was first held in 2021. It evolved out of the longstanding New Horizons and Beyond the Horizons annual joint humanitarian assistance exercises in Latin America and the Caribbean.
“The importance of this large-scale global exercise cannot be over emphasized,” said U.S. Air Force Colonel Kirk Stahlbaum, the commander of the Joint Task Force overseeing Resolute Sentinel 22. “Our efforts to date will enhance education, health, and sanitation for thousands of Central Americans, as well as bolster their military and security forces and their ability to operate with United States partner forces in the years to come.”
