Yama Sakura 87 marked several historic firsts in multinational military cooperation, bringing together forces from Japan, the United States, and Australia in a trilateral command post exercise.
This iteration ran concurrently with the U.S. Army’s Warfighter command post exercise and involved operations across Japan, Hawaii, and Washington.
The exercise focused on joint human, procedural, and technical interoperability for Cross-Domain Operations and Multi-Domain Operations. Working alongside I Corps and CIO/G-6, M42 demonstrated capabilities for distributed command and control and secure information sharing across disparate networks.
The lessons from Yama Sakura continue to inform how we think about coalition environments, cross-domain exchange, and the infrastructure required to establish a common operational picture without assuming a single shared network.
