This podcast episode discusses the challenges that the US military is facing in its supply chain due to the war in Ukraine. The military has been sending large amounts of ammunition to Ukraine, which has depleted its own stocks. The US military is now trying to ramp up production of ammunition, but it will take time to reach the desired levels. The episode also discusses the challenges of just-in-time production in the military and the perennial debate over whether countries should maintain a full standing army and stockpile supplies in case of emergencies.
