What feature does the Chinese PGO-7 version include that the Soviet version does not?

The correct choice indicates that the Chinese PGO-7 version is equipped with a personnel range finder, which is a feature not found in the Soviet version. This aspect enhances the usability of the weapon system by allowing operators to more accurately estimate the distance to personnel targets, ultimately increasing the effectiveness of engagements.

Having this range-finding capability allows for better precision when firing, ensuring that the weapon can be used effectively in various combat scenarios. The inclusion of this feature reflects advancements in design and user requirements that the Chinese version sought to accommodate, thereby differentiating it from its Soviet counterpart.

Other options, such as higher magnification, a temperature compensator knob, and night vision capabilities, might enhance the functionality of weapon systems but do not specifically pertain to what distinguishes the Chinese PGO-7 version from the Soviet version regarding personnel targeting. The unique feature of the personnel range finder contributes specifically to target accuracy and tactical versatility.
