# Harnessing the Potential of Emerging Technologies to Break Down Barriers in Tactical Communications
## 4 Use Cases
### Use Case 1: Combat Search and Rescue  
This scenario pertains to a military air rescue operation carried out amidst wartime conditions, either within or in close proximity to combat zones. The primary aim of the \begin{table}

Table 3: Association between use cases (UC) and emerging technologies for tactical scenarios. rescue operation is to locate, communicate with, and retrieve aircrew downed during combat and any potential survivors. Other operational tasks within this use case could be supplying equipment and materials to train the soldiers in everything necessary for the rescue mission, carrying out medical evacuation operations, and configuring all the necessary equipment for the correct and efficient deployment, among others. Any military tactical scenario needs reliable, secure, and fast communications. Fifth-generation technology allows this reliable connectivity, reduces latency, and, above all, has wide bandwidths, which is especially important in scenarios where operations are extremely urgent since many lives are at stake. The exchange of information and connectivity, for example, between military tactical radios, which make it possible to locate and communicate with troops in remote locations, can potentially reduce response time in emergencies such as rescues. IoBT allows great technological development in military operations, battle scenes, equipment production, and war machinery, among others. Moreover, it uses sensors, wearables, and UAVs and makes use of edge computing, reducing communication latency between IoT devices and managing network bandwidth for better operational efficiency.
