I've encountered an issue with my model's texture's within blender.
I was able to apply one of the TGA files by heading over to UV/Image Editor and selecting a file called Reptile_B1_Diff.tga
The file itself displays the entire model's textures. However, there are still other textures files that need to be included such as the eye ball and some kind of blue/purple body to my model as well.
But whenever I open those files containing the necessary texture, the entire model changes to the selected texture and doesn't stay with the texture that it had before.
