Which system provides real-time tracks, target databases, and service-specific fires information into a single software application?

The correct choice is JADOCS, which stands for Joint Automated Deep Operations Coordination System. JADOCS is designed to integrate real-time tracking, target databases, and specific fires information into one cohesive software application. This capability is crucial for enhancing situational awareness and operational efficiency in joint and combined military operations.

By consolidating various operational data into a single interface, JADOCS allows military personnel to coordinate effectively across different branches and services, ensuring that they have access to vital information in real time. This centralized approach enhances decision-making processes and facilitates an agile response during operations.

The other systems listed do not focus specifically on combining real-time tracking and target databases into a single application with service-specific fire information. Each of them may serve distinct functions or cater to different aspects of military operations, but they do not fulfill the requirements specified in the question to the same extent as JADOCS.
