Here are tons of files convertable for civ4 with blender. But be aware of high polycount I just will use files which wont exceed the size of 40Kb, this is still high but better than attaching a whole unit to another just to have another head. Not sure if I understand what you don't understand. With bits I mean attachable nifs like weapons or heads(!) to create new units with them in the nifviewer. If you want create headattachments for playing with the nifviewer remember to delete the animations.

....however, recently, i have wanted to add some extra flavor to mech and modern armor by making some modifications in blender to "vanilla" mech and modern armor NIF files, for example to make a modern british challanger tank (from modernarmor.nif) or various APCs, such as the german boxer, M113 or french VAB (from mechanizedinfantry.nif) i can get the nif in blender, i can choose and edit/delete edges, faces, etc, I can save as .blend file and models comes up normally in blender, BUT when i export to nif...."python script error: check console"
.....yes, my nif export script is set at 4.2.2.0
.....
..... if anyone with some experience can DL the .blend file and successfully export to NIF, it would be a GREAT help in being able to create new units (I seem to have the same trouble with mech, modern armor, mobile SAM, but NOT with "human-like" nifs, I have been able to export those)
