Question

During adjustments of a fire mission an observer spots round burst left of the target along the OT line. The observer measures the angular deviation as 70 mils. His deviation spotting is _______________.

Answer 1

The observer's deviation spotting is referred to as “Left 70”, indicating that the round has deviated by an angular measurement of 70 mils to the left of the target along the observer-target line.

Step-by-step explanation:

When an observer spots a round burst left of the target along the OT (Observer-Target) line with an angular deviation of 70 mils, this means the round has deviated from the intended target point by that specific angle. In military terms, the deviation spotting would be referred to as “Left 70”. A correction would then be communicated to the firing unit to adjust the fire for a successive round, hopefully resulting in the rounds impacting closer to the target.


If such adjustments are deemed necessary, they would include a shift in the firing solution to compensate for the observed deviation, taking into consideration the angle and distance to the target in order to achieve the desired effect on the target.
