CircleCross scope port from WoT and the World of Tanks.
The author of the original mod for the World of Tanks and WoT - Andre_V

There are two versions of the sight marker available:
1 var - with a light green circle in the center.
2 var - without the green circle in the center.
3 var - without the green circle in the center, without the 2nd and 3rd sectors of the circle.
You can preview the 3 versions on the preview of the mod.

If the center of the marker does not match the center of the sight or there are visual errors in the game, be sure to write in the comments, I will fix it.
