Fire only at targets positively identified as hostile is indicative of which weapons control measure?

The phrase "Fire only at targets positively identified as hostile" is indicative of the weapons control measure known as "Weapons tight." This measure is applied to minimize the risk of mistaken attacks on non-hostile units, including civilians or friendly forces, by enforcing strict identification protocols before engaging a target.

Under this control measure, personnel are required to confirm that a target poses a clear and immediate threat and is indeed hostile before using their weapons. This level of caution is critical in complex operational environments, where the risk of collateral damage is high.

In contrast, the other options suggest different levels of engagement. For example, "Weapons hold" means that no engagement is allowed unless specifically directed; "Weapons free" allows personnel to engage any targets without prior identification as hostile; and "Weapons unsafe" typically refers to a condition where munitions cannot be fired due to safety concerns or disengagement protocols. Thus, "Weapons tight" best reflects the guideline of engaging only identified hostile targets.
