This one doesn't seem that active, does it? Probably an instance somewhere. Reddit does.

However, not every category like "Military" supports the Reddit .onion and it is monopolized by Google and not nearly as cool as Lemmy and the Fediverse.

This could be an interesting spot, but got to find regular contributors. I would like to hear from more vets and active duty myself. Could be a more conservative group on the whole though and would prefer other or no social media.
