Which component is NOT part of the physical dimension in the IE?

The correct answer is that the information gathering processes are not part of the physical dimension in the Information Environment (IE). The physical dimension primarily encompasses tangible elements such as systems, hardware, and infrastructure that support operations.

Command and control systems represent the physical systems through which military operations are coordinated and executed. Key decision makers are individuals who operate within the physical structures and systems, making decisions based on the information provided by those systems. Infrastructure supporting operations includes the physical facilities and networks that enable military functions, ensuring that all necessary elements are operational and effective.

In contrast, information gathering processes focus more on the procedural or cognitive aspects of collecting and analyzing information rather than the physical structures or systems. This distinction is important in the context of understanding how each component fits into the overall framework of the Information Environment.
