What does "interoperable" refer to in military communications?

In military communications, "interoperable" specifically refers to the compatibility of systems from different sources. This means that various communication systems and devices, even if produced by different manufacturers or designed for different purposes, can work together seamlessly. Achieving interoperability ensures that forces from different branches or allied nations can communicate effectively, share information, and coordinate operations without facing technical barriers. This capability is vital in joint operations, where diverse platforms and technologies must integrate to achieve mission success.

The concept encompasses hardware compatibility, software protocols, and operational procedures, allowing for effective communication across diverse military units. This ensures that commands can be relayed, and information can flow freely, enhancing overall operational effectiveness.
