〔記者涂鉅旻/綜合報導〕美國陸軍持續強化步兵機動火力,日前以1290萬美元(約新台幣3.9億元)合約,委由Global Military Products公司將「輕型天蠍」(Scorpion Light)81公厘機動迫擊砲系統,整合至ISV-U步兵班多用途車。這套系統主打「快打快撤」,可在停車後30秒內完成展開射擊,並力拚在2分鐘內完成停車、射擊、撤收及轉移,大幅壓縮遭敵軍反砲兵火力與無人機鎖定的時間。
根據外國軍聞網站「Army Recognition」報導,「輕型天蠍」並非追求提高M253型81公厘迫砲本身的彈道性能,而是將導航、射控及瞄準流程自動化。系統整合GPS、慣性導航、傾角儀與數位射控電腦,可自動計算射擊諸元,再由機電致動器調整砲管方位及俯仰角;射擊後重新瞄準約需3至5秒,轉換新目標約8至10秒,最後一發打完後,也可在30秒內完成撤收。
這套系統今年已在美菲「肩並肩2026」演習接受驗證,2套「輕型天蠍」在不到2分鐘內共發射20枚迫砲彈,展現短時間密集射擊能力。81公厘迫砲最大射程約6.5公里,首分鐘射速最高可達12發、持續射速約每分鐘4發;不過,美軍M253砲管搭配美規射控後的實際射程及射速,仍須視彈藥與系統而定。

除了射擊速度,將81公厘迫砲整合至ISV-U,也能減輕輕步兵的運輸負擔。美軍測試構型可同時搭載砲班、迫砲及72發砲彈,整車也可由CH-47「契努克」直升機運送,使機降部隊落地後,即可擁有可自行機動的曲射火力,不必再由官兵肩扛迫砲與大量彈藥。

At the 2026 Taipei Security Dialogue, Director of the American Institute in Taiwan Li-yan Koo pointed out that Taiwan can exert its unique asymmetric advantages to deter conflicts through the three fields of unmanned systems, mission command and social resilience, and emphasized that investment and reserve combat capabilities are the key drivers, citing the Ukrainian war experience as a reference.

A report by senior former defence officials released by the Sasakawa Peace Foundation on September 2 proposed allowing non-Japanese nationals to join Japan's Self-Defense Forces to address personnel shortfalls caused by declining birth rates and an ageing population. The government rejected the idea, citing public opposition to immigration and instead focusing on improving conditions for current personnel, supporting veterans, and expanding technology use like AI. Employers across Japan struggle to find workers, and analysts note the military lacks appeal for young people, while other countries like Britain recruit Commonwealth citizens.

Japan is constructing a new defence hub in Kure, Hiroshima prefecture, on a former Nippon Steel site to enhance military resilience for a potential Taiwan conflict. The facility will combine logistics, production, and military functions to sustain forces during prolonged fighting. Experts say this reflects a shift from deterrence to endurance planning, as Tokyo prepares to defend itself if deterrence fails. Prime Minister Sanae Takaichi warned a Taiwan contingency could be a 'survival-threatening situation' for Japan. The hub underscores Japan's accelerating military build-up amid concerns over China's growing influence in the western Pacific.

The US struck multiple Iranian oil tankers near Jask and Kharg Island in response to missile attacks on a Navy warship, triggering crew evacuations and retaliation warnings.

German Defense Minister Pestorius announced that more "Patriot" air defense system interception missiles will be allocated from the Bundeswehr inventory to support Ukraine in resisting Russian missile and drone attacks, and called on other allies to jointly review the inventory and provide assistance.

The Guangdong Provincial Department of Emergency Management's first helicopter rappelling skills training for professional emergency rescue teams in 2026 concluded in Zhuhai. 30 team members passed the actual combat subject assessment to improve the professional air assault rescue skills in response to major emergencies.
