Here's why:
* Latin is a dead language: It's not spoken natively anywhere in the world. While some languages like Italian, Spanish, French, and Portuguese have Latin roots, they are distinct modern languages.
* Military languages: While some countries may have military units that use German, it's not the official language of any military globally. Most militaries use the language of their respective countries.
It's possible you've come across a fictional scenario or historical reference where this might be the case, but in reality, such a combination doesn't exist.
