Why randomized familiar ranks feel incoherent

What do you think of a fictional military that uses United States rank titles in a randomized order?

It is unconvincing because the familiar titles already carry roles and meanings that an audience will not simply forget.

The question imagines a fictional force using United States rank names in random order. Each title has accumulated an expected role and place in a hierarchy. Readers bring those associations with them and are unlikely simply to forget them when the labels appear in fiction. Rank names communicate institutional relationships rather than serving as arbitrary steps.
