What is the maximum effective range of the AT-4?

The maximum effective range of the AT-4 is 300 meters. This range is established by the weapon's design and operational capabilities, allowing infantry soldiers to engage armored vehicles or fortified positions effectively from a safe distance. The AT-4 is a shoulder-fired, single-shot, disposable anti-tank weapon that is optimized for close to medium-range engagements.

At 300 meters, operators can accurately target and engage threats while minimizing the risk to themselves due to the weapon's guided capabilities. This maximum effective range ensures that soldiers can utilize the AT-4 effectively in combat scenarios while still adhering to safety protocols and engagement strategies that keep them out of harm's way.

By contrast, the other options do not represent the AT-4's capabilities accurately: 2100 meters far exceeds its effective range, while both 10 meters and 30 meters are far too short for effective use, as the weapon is designed for engagements at a distance that provides both accuracy and safety from return fire.
