MILITARY LOGISTICS AND SUPPLY CHAIN RESILIENCE The U.S. military's supply chain depends on approximately 50,000 defense contractors across a fragmented industrial base. During the Cold War, the DoD maintained redundant suppliers and domestic production capacity; today, critical components like rare-earth elements source primarily from China (60-80% of global production). The 2020 COVID-19 disruptions exposed vulnerabilities when semiconductor shortages delayed weapons system production by 6-18 months. This matters because near-peer competitors like Russia and China have vertically integrated supply chains and strategic stockpiles, while NATO allies face similar fragmentation—creating asymmetric advantages in rapid mobilization scenarios and potential leverage points during conflicts that extend beyond traditional combat timelines.
