Which method of estimating distance uses the following equation: Elapsed Time between impact and sound x 350 = distance?
Flash to Bang
A ___________ is the observer’s determination of the location of the burst, or the mean point of impact of a group of bursts, with respect to the adjusting point observed along the observer-target line.
Spotting
The _______ consists of the type of mission, the size of the element to fire for effect, and the method of target location.
