The technology associated with 5G and future 6G networks is challenging for military communications in tactical scenarios. This work has selected and analyzed a group of leading technologies that allow tactical networks to evolve. The virtualization of networks with 5G helps to guarantee greater security. These developments are vital in improving the feasibility of truly network-centric operations for military applications. Software-defined networks, IoT, blockchain, Artificial Intelligence, semantic communications, or neuromorphic processors help increase communications performance. These technologies have improved ten classic use cases in the military field. This work is an analysis to serve as a starting point for new scientists to open up new lines of research. It is not merely a compilation but an analytical basis for future work.
