Turm 3 unable to rangefind

Hi all,

Not sure if it is just me, or I have missed something, but the Turm 3 is unable to rangefind (or, atleast I am unable to make it rangefind). I have checked my controls and tested on other vehicles, and there is no problem there. Is this a known “feature”?

The Turm III haven’t telemeters.
You can use gunner distance estimation, but that don’t set the distance on your gun.
