It’s just typical pretentiousness common in government related things, by people who use it as cover for mediocrity, especially when talking to laypeople.
It’s intentional in order to create a mysticism about government and military matters to impress the commoners.
There’s even legislation and policy directives to require the government to use and require common language instead of jargon. In typical government action fashion it is of course only effective in a very limited, below threshold manner, but it also cannot affect the people in the private sector so use it to feel important to commoners and project their mediocrity to those in the know.
It’s very much the same kind of behavior as is common in the financial sector to cover and obscure and obfuscated the scheme.
