The form of a unified Japanese Federation military is nearing completion. As a fundamental defense strategy, the Soviet Union is designated as the main adversary, and the primary mission is the defense of the Siberian Republic, which is the driving force of vitality for the Japanese economy. The doctrine of this military strategy emphasizes the efficient deployment of combat power by networked units and the neutralization of enemy forces by targeting enemy command centers. This outcome stems from the consideration of how to thwart the Soviet offensive with small-scale units in a war where numerical disadvantages are anticipated.
The challenge lies in the disparity of training between the Self-Defense Forces and the relatively young militaries of the states. Consequently, the training of units facing the Soviet Union in Siberia was conducted urgently. Furthermore, in the case of ground forces, heavy equipment such as tanks, armored vehicles, and specialized artillery (field guns) were emphasized to compensate for numerical disadvantages.

Japanese Combined Armed Forces
Under the command of four general headquarters, the SDF and seven states' military units are operated in an integrated manner. Even units primarily tasked with ground attack within the aviation forces are incorporated into this structure. Units primarily focused on air defense are consolidated into three air defense regional commands. Maritime forces are divided into mobile operational units and security units under the management of each joint command, and they are operated accordingly.

- Tactical Fighter Squadron: Equipped primarily with F-15s and F-3s. Due to operational cost and performance differences, their main deployments are mainly in mainland Japan.
- Strike Squadron: A ground attack mission unit equipped with the F-35As and F-5s. The F-35As are often used for reconnaissance missions.

Maritime Forces (major naval vessels)
Basically, it is formed around the JMSDF as the core, and most of the navy is composed mainly of security vessels.

Notes
*1: These B-1 and B-2 bombers are made by the Japanese.
The B-1 is designed based on the P-1, with its anti-submarine equipment removed and the bomb bay reinforced. This solid design allows for swift operation.
The B-2 bomber is developed as an entirely new zero-start bomber, modeled after the American-made B-52. Initially, the development also considered a supersonic bomber design using a flying wing concept. However, it was determined during the planning phase that there wasn't sufficient accumulated technological capability for such development. Concerns about the risk of development delays led to the finalization of a conventional design for the bomber.
*2: A carrier-based fighter based on the original proposal for a multi-purpose STOL aircraft during the development of the F-5. Developed for 30.000-ton aircraft destroyers. Fundamental research and development were conducted, and the reuse of various technologies developed for the F-5 allowed for early practical implementation.
*3: The Yukikaze-class destroyer is a large destroyer developed as a successor to the Murasame-class destroyer and the Arleigh Burke-class destroyer of the Republic of Guam.
