What action best supports accurate target designation when lines of sight are limited?

• A. Rely on autotargeting.
• B. Use direct line-of-sight marking only.
• C. Use offset marking to help guide fires.
• D. Engage with no marking.

Answer: (C)

When lines of sight are limited, you need a marking method that ties the target to something you can actually see and measure from. Offset marking does exactly that by designating a visible reference point and then giving a known offset to the target relative to that reference. The observer marks the reference and communicates the distance and direction to the target from that point. The fires team uses that information to compute the target’s location and adjust fire accordingly, even though they aren’t directly marking the target itself. This keeps aiming accuracy high when terrain, smoke, or distance prevents direct designation. Relying on autotargeting isn’t always feasible, direct line-of-sight marking may not be possible, and firing with no marking leaves the team without a reliable cue to guide weapons. Using offset marking provides a dependable bridge between what can be seen and where the target actually is.
