An important tactical requirement for modern mobile communication networks is that mobile nodes function even in areas without coverage from radio masts or base stations. These fully mobile networks have from fundamental physical reasons, sometimes sharply limited capacity, compared to commercial networks with base stations. It is therefore important that the radio network can manage available resources effectively. Mobile ad hoc networks are wireless multihop networks whit the ability to dynamically adapt to changing conditions. A great tactical gain in ad hoc networks is that they can function independently of base stations and other fixed infrastructure if required. The report aims to briefly describe some of the tactical communications networks that is being developed nationally and internationally, common tactical user requirements and the implications and issues that this entails. The report concludes by identifying and describing three important issues for further study. The first is the priority-based resource allocation in ad hoc networks. Since the resources are limited, we want to allocate them to the services that allow the user benefits to be maximized. The second case is broadcast technologies in networks with variable data rates. Much of the traffic in tactical networks are broadcast by nature, there is a clear need to streamline the distribution of such traffic. The third issue is interactions between waveforms. Future software radio will also be able to handle multiple waveforms such as A TDRS, TDRS B, Essor, WOLF, and COALWNW
