I noticed the same thing. I tried CS models, but took a chance to test DOD and TFC as well. No one of the models are not animated.
MD2 works fine and the animation works perfectly. Many of modellers have export for MD2 which is good format to make skinned mesh-deformation based animations.
I loaded those MDL models I mentioned before to 3d exploration and the animation plays well. I noticed the MDL format does not store the animation as keyframes, but the animation data is under headers.
Unfortunately I don't know any program that is able to convert MDL (attaching animation) to MD2.
The evil plan is now even closer!
