This is the problem, I have extracted the t72 texture manually, using the "010 Editor"; if you open the datapack.cd with the editor you will read data like this "su1t72_armor, data\textures\armor" this is the position in the file where begin the texture of the t72, and the file ends where there is "AZRC". So you must copy this part of the datapack.cd, open a new file (in the 010 editor) and then use the menu tools->operations->binary invert; at this point select the hex option and then OK. This operation will decrypt the file, in fact all the data in the datapack.cd are "inverted". Now save the file in the t-72\data\textures\armor folder with the name su1t72_armor.tga
