Ah, sorry, my interpretation about the explanation in the dictionary seems to be wrong.
副助詞 isn't used only for advervial usage. こたつなどを出す is also an example of 例示, but this is not adverbial. こたつなど出す is also valid, so の is disappeared behind など is one of the ways of interpretation in your example sentence and my one. Another interpretation "機体を隠して夜間に移動させる is an example of 情報統制を徹底した" would be also possible, though.
