The United States and Sri Lanka began a five-day joint humanitarian assistance and disaster response exercise on Monday, bringing American and Sri Lankan military personnel together for training centred on Sri Lanka Air Force Base Katunayake and in Kandy.

Atlas Angel II runs from August 31 to September 4. It involves personnel from the Sri Lanka Air Force, the Montana National Guard and US Pacific Air Forces, with observers from the United Kingdom and Bangladesh also taking part.

Training covers C-130 aircraft maintenance, urban search and rescue, incident command systems, construction engineering, landslide response, and chemical, biological, radiological, nuclear and explosive hazard management. The Daily Mirror reported the programme is focused on improving communication, coordination and interoperability during real-world disasters.

The Montana National Guard delegation is led by Brigadier General Trace Thomas, Assistant Adjutant General for Air, and Brigadier General Renea Dorvall, Assistant Adjutant General for Army.

What the two commanders said

US Ambassador Eric Meyer framed the exercise as practical rather than ceremonial. “The United States and Sri Lanka have a shared interest in being prepared when disasters strike. Atlas Angel is a strong example of what our partnership looks like in practice — Americans and Sri Lankans training together, sharing expertise, and learning from one another,” he said, according to NewsFirst.

Air Force Commander Air Marshal Bandu Edirisinghe said the exercise showed why disaster cooperation cannot be organised along national lines. “Natural disasters know no borders. They do not recognize economic strength; they affect us all. Through Atlas Angel II, we have redefined what humanitarian assistance and disaster relief operations mean, with multiple nations coming together to learn how we can collectively assist people wherever they may be,” he said.

The exercise is among the first public engagements for Meyer, who arrived in Colombo on August 24 after being sworn in earlier this month.

A second run with a changed line-up

Atlas Angel II builds on the State Partnership between the Montana National Guard and Sri Lanka established in 2021 under the US Department of Defense’s State Partnership Program, and on a memorandum of understanding signed in November 2025 covering disaster response, aviation and maritime security. NewsFirst reported that memorandum was signed between the Montana National Guard, US Coast Guard District 13 and the Sri Lankan Armed Forces.

The first Atlas Angel ran from August 5 to 9, 2024, and differed in composition: it included members of the Maldives National Defence Force, fielded more than 70 US personnel and two C-130 Hercules aircraft, and culminated in a crisis management exercise, according to the US Embassy’s announcement at the time. This year’s exercise drops the Maldivian element and adds British and Bangladeshi observers. Neither NewsFirst nor the Daily Mirror noted the change, and neither reported how many US personnel or aircraft are taking part this time.

NewsFirst linked the exercise to Cyclone Ditwah in December 2025, when two US Air Force C-130J Super Hercules aircraft were deployed to move emergency supplies. That storm also shaped a three-day US-Sri Lanka disaster preparedness workshop held in Galle in June, and the Montana partnership was among the subjects of a Sri Lankan delegation’s visit to the state in April.

Musicians from the US Air Forces Band of the Pacific will also perform with Sri Lankan counterparts during the exercise.
