Gray Tiger II by ODA, Painted Gray and tricked out with detailing (including Iron Cross logo, spare tracks). Just unzip the file and either use my Mod Util to install the mod or just copy the directory into your original game's mods directory (make a mods directory under your game directory if you don't have one) and then start up the original RoN, start a game and then select the "ODA Grey King Tiger V2.0" from the mod menu. If you want to just plain replace the old file, you can find the file named KingTigerGrey_ODAv2.tga, for the gray version or KingTigerSnowgrey_ODAv2.tga for the snow camo version inside the mod's art directory. Rename the one you want to kingtiger.tga. Find the File with that name in the original game's art directory. Make a backup of that, and then replace it with the modded file.
