What core principle of military doctrine ensures interoperability and coordination between different units?

The core principle of military doctrine that ensures interoperability and coordination between different units is standardization. Standardization involves establishing common terminology, procedures, equipment, and training standards across different units and branches of the military. This allows units to communicate effectively, operate together seamlessly, and support each other during military operations. Common terminology ensures that all personnel understand the same terms and concepts, reducing the risk of miscommunication and confusion. Standardized procedures ensure that units follow the same protocols for planning, execution, and reporting, facilitating coordination and collaboration. Standardized equipment allows units to share resources, maintain equipment more efficiently, and operate using compatible systems. Standardized training ensures that all personnel receive the same level of training and are proficient in the same skills, enabling them to work together effectively. For example, if different units use different radio frequencies or communication protocols, it will be difficult for them to communicate with each other during an operation. Standardization ensures that all units use the same communication systems and protocols, enabling them to communicate effectively and coordinate their actions. Standardization therefore creates a common operational picture, facilitates information sharing, and enables different units to work together as a cohesive force, ultimately enhancing the effectiveness of military operations.
