What sensor provides 24-hour all weather tactical SIGINT to the brigade Commander's area of interest?

The correct answer is the POR-B sensor, as it is specifically designed to provide continuous tactical Signals Intelligence (SIGINT) capabilities over the brigade Commander's area of interest, regardless of the time of day or weather conditions. This capability is essential for maintaining situational awareness and ensuring effective command and control in various operational environments.

The POR-B sensor's 24-hour operational capability allows for uninterrupted monitoring and collection of signals, which can be crucial for identifying and analyzing communications, electronic emissions, and other forms of signal activity. Its all-weather functionality ensures that the brigade can rely on SIGINT support even in adverse weather conditions, enhancing operational effectiveness.

In contrast, the other options serve different purposes or may not provide the same level of continuous tactical SIGINT. The Puma, for instance, is typically an unmanned aerial vehicle better suited for reconnaissance and surveillance rather than focused SIGINT tasks. The JBC-P (Joint Battle Command-Platform) serves as a command and control tool enabling better battle management but does not specialize in SIGINT. The ATN (Augmented Tactical Network) functions primarily as a communication network to support various operations rather than directly providing SIGINT capabilities.
