When entering operations after initialization, what mode does the AN/TPQ-36 default to?

The AN/TPQ-36 Firefinder Radar defaults to hostile fire mode after initialization. This mode is critical for the radar's primary function, which is to detect and locate enemy artillery fire. By entering hostile fire mode, the system actively scans the environment to track incoming projectiles, allowing for timely and accurate response actions.

In this mode, the radar focuses on identifying the source of hostile fire to facilitate counter-battery operations. This ensures that the field artillery can effectively target and neutralize the threat. Hostile fire mode is essential for providing information to the command staff on enemy positions and to safeguard friendly forces.

The confusion around other modes stems from understanding the various operational capabilities of the AN/TPQ-36. While neutral mode, observation mode, and search mode have specific purposes and applications, they do not align with the immediate operational priorities of detecting and responding to artillery attacks post-initialization. Thus, the defaulting to hostile fire mode supports the radar's role in combat scenarios where rapid detection of threats is necessary.
