This happens both with the player and with the AI - very similar to limiting the life of a missile or limiting the distance of flight - which is essentially a mistake.
If the shot was alredy fired, then the target was locked. Without a target capture, the Titan is unable to shoot at all. If the target was locked, then the AT-missile knows where to fly and this missile should reach the target at any distance and under any circumstances, if there are no obstacles on the way to the target.
But instead, user periodically watches missile explode in the air one by one, as if it were a festive firework! [[ https://feedback.bistudio.com/T134499 | AI has incredible AT-Titan reload speed ]] - can shoot thee missile in a row! One, two, three - And all of this missiles, one by one, explode in the air - such a sight is not for Arma3.
Dear developers, if the game requires a distance limit for Titan, then use the ban on capturing the target. Missiles should not explode uselessly in the air, as this wastes the soldier’s ammunition in vain
