Imperial interoperability through common standards

Common standards would help Britain and the Dominions combine their forces. Compatible ammunition calibres, logistical methods, and operating practices would allow units from different services to work together and reinforce one another. NATO provides a comparison because its standards organization contributes to allied cooperation. The counterfactual imperial system would lack the modern alliance's general technological advantage, and even NATO's advantage is not universal across every field. The practical effect of common standards on a geographically dispersed force makes the comparison useful.
