Military code names and national character

Last year, I posted a brief thought about how different armies name their major operations. Apparently, there has been much made of this in previous wars, as the Imperial Armorer reflects:

The whole naming thing started out as a security measure. It gave a shorthand way to refer to something in messages, whether a weapon system, troop movement, location, operation, intel asset, etc , so people in the know would understand what you meant, without larding up messages with a lot of text, as well as revealing info to interested eavesdroppers. Jargon for security.

Like the Manhattan Project for the atomic bomb. Operation Overlord for the invasion of Europe. Utah Beach, Operations Olympic and Coronet for the planned invasion of Japan. "Tank" for the Tank (crates with the first tanks in them were marked "Water Tank" — the name stuck). Infinite Justice Enduring Freedom — the take-down of Afghanistan. The military aren't the only ones, either; e.g., Microsoft's "Longhorn" which is now officially "Windows Vista."
