S!, As I learn Photoshop, I took a crack at creating a replacement for the "custom_photo" found in each tank. This is very similar to what is floating around for individual planes. I essentially replaced the custom_photo with a small range chart. The chart is based on 4 & 5 mils when measuring distances through binoculars (nocs) & gun sights.     If you want to this, you can find it here: https://cdn.discordapp.com/attachments/904425611253145620/90595512723036569
