KS 27 | Bilateral Integration

Official Statements

• 3d Marine Division, November 9: “U.S. Marines with 12th Marine Littoral Regiment, 3rd Marine Division, worked alongside the Japan Ground Self-Defense Force as part of Exercise Keen Sword 27; conducting a series of bilateral training events across the Okinawa, Kagoshima, and Oita Prefectures, Japan, Oct. 14 - Oct. 30. The training provided Marines throughout the regiment opportunities to strengthen bilateral relationships, enhance operational coordination and improve interoperability across diverse training environments.

  Adverse weather conditions reduced visibility complicated navigation, requiring Marines and JGSDF members to adapt and coordinate their movements. These challenges, combined with language barriers and differing operational approaches, tested the adaptability of both forces and reinforced their ability to operate as a cohesive unit.

  “It’s really important for us to train in Hijudai [Maunever Area] because we get to meet up with our bilateral partners and enhance the cohesion,” said Cpl. Jalen Evans, an intelligence specialist with 12th MLR. “It is something you really see within the lines with the embarkers, the intelligence, and the current operations; they all merge together.”

  Differences in tactics, communication and operating environments provided opportunities for U.S. Marines and JGSDF personnel to improve exchange knowledge, refine coordination and strengthen bilateral cooperation. Working through these challenges reinforced the importance of shared problem-solving and adaptability in maintaining combat readiness.

  “The exchanging of our ideas is important. Even if someone has an idea that doesn’t work out in the moment, it helps us build off of each other and can be reworked to fit a certain tactic later,” said Cpl. Evans. “That small seed that was planted lets us work with our partners to find a way to make it fit and therefore lets us be in sync with them.”

  Operating across the Sakishima Islands provided Marines with 12th MLR opportunities to gain hands-on experience navigating the region’s terrain alongside their Japanese counterparts.Training in unfamiliar environments allowed both forces to assess how terrain influences tactical operations, strengthen situational awareness and refine planning for future bilateral exercises.

  “It really helps us get situational awareness as far as platoons spread out across their defensive positions and it gives them a good opportunity train in any enviornment” said by Cpl. Ryan Martin, an intelligence specialist with 12th MLR. “The Hijudai Maneuver Area is really good place for that sort of thing. “

  Through Exercise Keen Sword 27, U.S. Marines and JGSDF personnel overcame environmental and operational challenges while strengthening bilateral coordination. The training reinforced the importance of coordinated planning, shared tactical knowledge and the ability to operate effectively alongside allied forces, contributing to continued interoperability and readiness throughout the Indo-Pacific region.”
