Part standardization isn't just bolts and major assemblies but also things like test stands, jigs, and everything else needed to repair something. Every repair bay needs for example a shop crane. Every division will have X number of shop cranes all their maintenance units. If there's a particular model shop crane that works with every engine for every vehicle in the division that's awesome. They just need X shop cranes. But then they get assigned a new type of truck. Its engine is bigger and better than the old model. Unfortunately the existing shop cranes are too small to handle lifting this new engine. Now the division needs a mix of shop cranes and enough where every motor pool has every shop crane necessary to fix any vehicle that comes in.
