What is one vulnerability in military communication systems?

The correct choice highlights a critical vulnerability in military communication systems: susceptibility to cyber attacks and hacking. Military communication networks are often integrated with advanced technologies, making them potential targets for cyber adversaries who seek to intercept, disrupt, or manipulate communications.

This vulnerability stems from the increasing sophistication of cyber threats, including malware, phishing, and denial-of-service attacks, that can compromise security features designed to protect sensitive information. If an adversary successfully breaches a military communication system, it could lead to significant operational failures, loss of critical data, or even unauthorized access to command and control capabilities, thereby jeopardizing mission success and national security.

Other options present considerations that may impact military communication systems, but they do not represent inherent vulnerabilities in the same manner as the susceptibility to cyber threats. For example, while high maintenance costs and limited range can affect efficiency and operational capability, these factors do not directly compromise the integrity or confidentiality of communications as cyber vulnerabilities do. Additionally, exclusivity to military use does not inherently indicate a weakness in the system itself; rather, it may limit exposure to public threats, thus affecting the assessment of vulnerability related to security risks.
