Cinematic_Jogger and Cinematic_Farmers are unused units made up of the models in Shogun 2's cinematics. Cinematic_Jogger contains the earbud toting joggers you see at the end of the Shogun 2 victory cutscene, while cinematic_farmers consist of the farmers you see in the ROTS intro cutscene.
I made a couple of videos showing off how cinematic_jogger and cinematic_farmer (along with other units with the cinematic_ prefix) look like in battle:
You'll notice in the second video that there are also businessmen and female joggers. This is made possible by modifying the unit_variance tables.
