I figured it out open WarThunder>Saves>(some random numbers)>production and you will see user sights.
Iirc i got message that they relocated it to another folder after the new update, if im not mistaken there is an option to open the files in game
do you know where to find it
Iirc on the options menu, cant check exactly currently but it should be there
looked every where still not seeing it, i just dont get why gaijin changed it again
