What FDC command will the FO receive after sending a CFF as "DNL" or after establishing a priority target?

The command the Forward Observer (FO) receives after sending a Call for Fire (CFF) with a designation of "DNL" (Danger Close), or after establishing a priority target, is "Laid." This command indicates that the gun line has prepared the artillery piece and aligned it to fire on the designated target.

The term "Laid" specifies that the artillery unit has adjusted the aiming point according to the fire mission requirements and is ready to fire once given the command. This is a crucial step that confirms to the FO that the artillery is set and will effectively engage the intended target when directed.

The other options refer to different statuses relevant to the firing process but do not appropriately describe the state of readiness communicated to the FO following a CFF marked as "DNL" or a priority target establishment. "Ready" typically signifies that the unit is prepared and may not be specifically aligned, while "In Position Ready to Fire" denotes that preparations have begun but not necessarily completed. "Aimed On" would relate to a specific targeting situation but does not accurately encapsulate the specific action indicated after a CFF as "DNL." Thus, "Laid" is the precise command that indicates readiness to engage the enemy target effectively.
