Triggers are an essential part of fire plan development for offensive operations; what is the basic computational formula (math step) for triggering the initiation and shifting of fires?

• A. [processing time (s)+transmission time (s)]=total msn time x enemy speed (m/s)
• B. [processing time (s)+transmission time (s)+TOF(s)]=total msn time x enemy speed (m/s)
• C. [processing time (s)+transmission time (s)+TOF(s)]=total msn time divided by enemy speed (m/s)
• D. [processing time (s)+transmission time (s)]+TOF(s)=total msn time + enemy speed

Answer: (B)

At the heart of firing plan timing is matching the projectile’s arrival with where the target will be. To do that you must include every delay before the round lands: the time to process the target data, the time to transmit the fire mission, and the projectile’s time of flight. Those are the delays that push the shot forward in time, and they must be considered together with how far the enemy will move in that same interval. The correct approach sums processing time, transmission time, and time of flight, and then sets that total against how far the enemy will travel during that same total time (enemy speed multiplied by the total time). This ensures the lead is accurate: the fire lands where the target will be, not where it is now. If any of those time components are left out or the relationship is altered (for example, omitting TOF or using a different operation), the timing would be off and the fires would miss or lose their effectiveness. In practice, you’re planning for the target’s movement during the entire latency from observation to impact, so including all time components and tying them to the target’s movement is essential to proper triggering.
