> Note to self: when manufacturing tanks, use UUIDs as identifiers, not sequential integers. The post-war Soviet aircraft industry was saddled with ridiculously convoluted Construction Number schemes in order to defeat such analysis. They varied by type, model and factory. Here's an example for one model built in one particular factory: All start with 353 plus three more digits which indicate the sub-type (242=Mi-24V, 246=Mi-24D etc) The seventh digit seems to represent the quarter built while the eighth digit seems to represent the year built. The last five digits as the famous post 1974 random nonsense number. They only abandoned the schemes in the early 1990s.
