Militaries use their own cryptographic algorithms, those of a private third party, or ones that are openly available.

But fear of a backdoor having been planted in publicly-available encryption protocols scares them--even though it is technically possible to analyze cryptographic primitives and establish whether or not they are dorked.

• Is there any other advantage in hiding the algorithms and protocols a military uses for its systems?

Militaries use their own cryptographic algorithms, those of a private third party, or ones that are openly available. However, fear of a backdoor having been planted in publicly-available encryption protocols scares them even though it is technically possible to analyze cryptographic primitives and establish whether or not they are dorked.

Is there any other advantage in hiding the algorithms and protocols a military uses for its systems?

They sometimes use their own cryptographic algorithm or use the third party's and sometimes use open community encryption algorithms.

But fear of being a backdoor planted in public encryption protocols scare them. Although it is technically possible to analyze crypto and find the structure, it is hard to believe, for instance, The army of a Europian country uses an encryption protocol designed in the USA.
The question remains is:
