Core Viewpoint - The recent "Han Guang" military exercise in Taiwan marked the longest and largest scale in recent years, showcasing new military equipment and strategies aimed at countering potential threats from mainland China [1][2][4]. Group 1: Exercise Duration and Structure - The "Han Guang" exercise duration was significantly extended to 10 days, with a focus on realistic combat scenarios and a shift in operational concepts compared to previous years [2][5]. - Traditional exercises typically lasted around 5 days, focusing on various stages of defense against a hypothetical invasion, but this year's exercise included new phases such as "depth defense" and "sustained operations" [2][5][6]. Group 2: Tactical Changes and Urban Warfare - The exercise introduced urban combat scenarios, reflecting a shift towards engaging in densely populated areas, which may resonate more with the Taiwanese public [6][12]. - The definition of "depth defense" was notably shallow, with the military considering positions just a kilometer from the coast as part of this strategy, raising questions about the effectiveness of such a defense [8][12]. Group 3: Mobilization and Reserve Forces - A significant mobilization of reserve forces occurred, with the entire 206th Infantry Brigade participating, marking a first in scale for such exercises [13][14]. - The mobilization process revealed contradictions in the readiness of reserve forces, as the time required for training and deployment may not align with immediate operational needs [17][18]. Group 4: Obstacles and Defensive Measures - The exercise emphasized the construction of various obstacles to impede enemy movement, but the practical effectiveness of these measures was questioned due to logistical constraints and the temporary nature of the setups [20][22][23]. - The use of civilian vehicles and materials for creating barriers highlighted the limitations of the exercise's defensive strategies, which may not translate effectively to real combat scenarios [22][23]. Group 5: New Weaponry and Military Capability - The exercise featured the introduction of new military equipment, including the M1A2T Abrams tanks and HIMARS rocket systems, showcasing Taiwan's efforts to enhance its military capabilities [24][28]. - Despite the presence of new equipment, the actual combat readiness of these systems remains in question, as many have not yet been fully integrated into the military [26][29].
