An interesting read, but poorly titled, either by the author or by their editors: The article isn't exclusively about cryptology, but about the broader field of SIGINT/COMINT. Two examples of non-crypto trends cited in the article: The increasing use of VHF by Chinese and North Korean forces, complicating intercept (VHF intercept has to be line of sight) and the near-complete ignorance of traffic analysis and of analysis of Chinese supply management, e.g., that they were ordering large quantities of maps of Korea, etc. The allies had the data to tell them the Chinese were preparing, e.g., presence of Chinese prisoners captured by ROK forces, but dismissed much of it. None of the above is cryptology.
