America has never fought a war without the help of allies. However, the closest ally in the Vietnam war was Japan, found 1,500 miles away and across the ocean. In Japan, the US had a major supply chain hub that supplied all of the world efforts in the war. The distance between these two countries presented a tremendous problem.
The American troops in Vietnam were having difficulties with the whole concept of supply chain management. Their manufacturing and logistics process to supply the war efforts had a lot of inefficiencies. Due to lack of management, forecast inaccuracy, and extensively long lead times, the troops in Vietnam began to stock-out of essential supplies, forcing them to plan out the war efforts differently and scale back in some instances.
