What equipment is used for tactical satellite communications?

The Tactical Satellite Terminal (TACSAT) is specifically designed for tactical satellite communications, making it the correct choice in this context. TACSAT enables military operations to communicate effectively in various environments, providing secure and reliable access to satellite communication networks. This equipment is crucial for maintaining command and control, especially in mobile and rapidly changing situations that military forces often face.

Other equipment, while they may have roles in communications, does not serve the specific purpose of tactical satellite communications in the same way that TACSAT does. For instance, the Remote Communication Module (RCM) may support communication functions but does not operate as a tactical satellite system directly. Similarly, the Satellite Relay System (SRS) and Portable Communication Center (PCC) serve different aspects of communication support but are not primarily focused on tactical satellite operations. Thus, TACSAT stands out as the specialized solution for this requirement.
