“During CARAT Indonesia 2022, we have learned so much about our TNI-AL and KORMAR partners,” said Col. Samuel L. Meyer, commander of 13th MEU. “They have welcomed us to their home with open arms, and as a result of their hospitality, we have strengthened our relationship and interoperability, both ashore and at sea. Over 28 years, we’ve developed our partnership, and this year’s exercise reassures our united commitment to free and open maritime environments within the region.”

An ashore bilateral coordination center provided exercise support to the at-sea and beach landing operations. The bilateral coordination center included an operational and support joint staff made up of Indonesian and U.S. service members.

“Combining this year’s exercise with a MAREX made CARAT Indonesia the most complex in recent memory.” said Capt. Sean Lewis, deputy commodore of Destroyer Squadron (DESRON) 7 – executing agent of Commander, Task Group (CTG) CARAT. “The binational staff ashore monitoring, supporting, and providing scenario injects to the combined task force at sea established a great foundation for future multilateral maritime exercises and operations.”
