What happens when signal support fails during a military operation?

When signal support fails during a military operation, confusion and misalignment among units typically ensue because effective communication and coordination are disrupted. Signal support encompasses all communication systems that enable units to share vital information, coordinate activities, and maintain situational awareness. Without reliable communication, units may not receive or understand commands properly, which can lead to misinterpretations or delays in response times. This breakdown affects the overall effectiveness of the operation, hindering the ability of commanders and soldiers to act cohesively and make informed decisions, potentially jeopardizing mission objectives. The other options imply positive outcomes or efficiencies, which are not realistic in the context of signal support failure.
