U.S. Marines test-fired 12 rockets [1] from a mobile HIMARS launcher during a rapid drill in the foothills of Mount Fuji this Wednesday.

The exercise demonstrates the military's focus on mobility and precision in the Indo-Pacific region. By practicing "shoot-and-scoot" tactics, the U.S. aims to reduce the vulnerability of its long-range artillery to enemy counter-battery fire.

The drill took place at a training range located in the foothills of the iconic Japanese mountain [1], [2]. This specific maneuver requires the crew to launch projectiles and immediately relocate the vehicle to avoid detection and retaliation. The High Mobility Artillery Rocket System, known as HIMARS, is a light multiple rocket launcher that can be transported by truck or aircraft.

Military officials said the purpose of the exercise was to keep Marines proficient with the HIMARS system [1], [2]. The system has become an increasingly important component of the U.S. military arsenal due to its ability to strike targets with high accuracy from significant distances.

The launch of 12 rockets [1] allows crews to practice the full cycle of engagement, from positioning and firing, to the rapid egress of the vehicle. Such drills are part of a broader strategy to enhance interoperability and readiness within the region.

Coordination with local Japanese authorities is required for such exercises to ensure safety and operational security. The use of the Mount Fuji training area provides a diverse terrain that simulates potential real-world operational environments.

The deployment of HIMARS in Japan underscores the U.S. strategy of distributed lethality. By mastering shoot-and-scoot tactics, the U.S. military reduces the risk of losing expensive assets in a high-intensity conflict, signaling a shift toward more agile, mobile defense postures in the Pacific theater.
