These are extra models found in the Half-Life .pak file that were not used in the game. Listed are each model's filename and animations. The AI code isn't set up to control all of these animations, but at least they have been done already. Valve has stated they will be releasing all the source files for models they didn't use, so hopefully someone can get some use out of these.
To view these in a level, create a monster_generic entity and in the 'model' properties put models/stukabat.mdl, for example. If you'd like to cycle through their animations, create a cycler entity and put models/stukabat.mdl in the 'model' properties. When you run the map you need to use a weapon to shoot the model to have it go to the next animation.
