Deleting preposterous fantasy units

[Dantman40]

I have been playing Darthmod 8.1 and one of its best features is removing units that belong more in "Lord of the Rings" than a game based on history, However there are still some atrocities against history that have to go. Chief among them are the ridiculous Briton head hurlers and the insanely overpowered, invincible Armored Elephants. The worst offenders, which utterly ruin the game IMHO are the God-like Chariots, which utterly own all cavalry. In reality war chariots were extinct by the time of the game, being far inferior to cavalry. Making them a super weapon is nothing short of retarded. The only charots that existed at the time were Briton light variety and they were missle platform only. How do I get rid of these game killers? I am a total newbie to messing with the files. I have tried deleting them in export_descr_unit and export_descr_buildings and it didn't work. What is the show-err command and how do I use it? What does commenting and uncommenting a unit mean and how do I do it? Any help would be greatly appriciated.
