True or False: The FDC announces SPLASH to the observer 5 seconds prior to round impact.

The correct answer is true. In artillery operations, the Fire Direction Center (FDC) communicates with observers to ensure they are prepared for the impact of artillery rounds. The term "SPLASH" indicates that a round is about to hit the designated target area. The standard procedure is for the FDC to announce "SPLASH" 5 seconds before the round is expected to impact. This allows the observer to take necessary safety precautions or move to a location where they can assess the effects of the fire. It also helps to coordinate the timing for any follow-on adjustments to fire or for subsequent requests for more fire support if needed. This practice is critical for enhancing safety and situational awareness during operations.
