The Defense Establishment’s AI Awakening
Amidst rising geopolitical tensions, the U.S. defense community is ramping up its focus on artificial intelligence (AI) to enhance military readiness and operational effectiveness. As adversaries like China invest heavily in AI-enabled warfare, the U.S. seeks to accelerate its own AI initiatives to avoid being outpaced.
These efforts are not just about technology but also about strategic adaptations to emerging forms of hybrid warfare. Enhancing AI capabilities will require a coordinated blend of innovation and policy reform, elements critical to maintaining dominance in a technological arms race.

Transformations in Military Artillery: HIMARS Overhaul
The U.S. Army’s 25th Infantry Division is replacing some of its traditional artillery pieces with the more modern High Mobility Artillery Rocket Systems (HIMARS). This decision marks a significant tactical evolution in military strategies, emphasizing mobility and rapid response.
HIMARS systems offer the ability to shoot and move swiftly, an advantage over towed artillery setups that typically have longer deployment times. This change reflects broader shifts in military doctrine towards flexible, quick-deploy systems that can leverage real-time satellite data for targeting and coordination.
