Abstract 5G networks are in advanced stages of trials across the globe and the deployment will begin as early as 2020. In this survey paper, the possible use cases of 5G networks in the military context is captured. After the introduction, the various key 5G technologies – mmWave, massive MIMO, HetNets, SDN, NFV, D2D Communication and the challenges in road to 5G are briefly discussed. The paper then focusses on security challenges and services as offered by the 3rd Generation Partnership Project (3GPP (5G)) Security Association 3 (SA3) group. Future battle space scenarios leveraging 5G technologies are covered next. Finally, the paper touches upon the present status of 5G deployment across the globe with special mention of 5G development efforts by the Government of India, the challenges and the opportunities ahead.
