Which command is responsible for the organization and training of computer and telecommunications activities?

The correct answer is based on the role and responsibilities attributed to the command in question. COMNAVCOMTELCOM, or Commander, Naval Computer and Telecommunications Command, is specifically tasked with overseeing the organization, training, and operational support of computer and telecommunications activities within the Navy. This command is vital in facilitating communication and technology systems, ensuring that personnel are adequately trained to handle these critical operations effectively.

Understanding the structure of the Navy, we realize that other commands listed focus on different specific areas. For instance, NAVFACSERV deals primarily with facilities and services, NAVCOMTELSPT is focused on telecommunications support, and NAVFACENGCOM is responsible for public works and engineering support. While all those commands play pivotal roles, they do not encompass the broader organizational and training responsibilities related to computer and telecommunications activities that COMNAVCOMTELCOM represents. Therefore, it is the command that uniquely fits the description of overseeing those specific functions.
