Can you please help us to understand why you believe the military has had *no* issues using existing comms? At face value this is an extraordinary claim and it flies in the face of examples of friendly fire such as https://www.bbc.com/news/articles/cj30zk1jnmno. I think the strongest possible statement would be "military comms are equal to or better than civilian alternatives with the exception that they do not bypass government record keeping laws" but I'm mostly unaware of what the military uses to communicate so it's difficult for me to accept this at face value with an explanation of the existing systems and their capabilities.

Some government software and processes are not pleasant to deal with such as the process of obtaining a green card so I don't really fault people for being skeptical of the existing systems without evidence of their robustness.
