Final answer:
Height of burst corrections for time rounds are determined to the nearest 10 meters to ensure optimal detonation altitude and round effectiveness.
Step-by-step explanation:
The height of burst corrections for time rounds are determined to the nearest 10 Meters. This level of precision ensures that the artillery rounds detonate at the optimal altitude to achieve the desired effect against the target. When dealing with artillery, precision is crucial, as the height of burst can significantly affect the round's effectiveness.
