I use them as balseraph city defenders as they fit the theme and with combat five they are awesome defenders.
Don't let em close to any dwarfs.
Elephants don't count as garrisons for purposes of eliminating "we demand military protection" unhappiness, so you do need a "real" troop to defend all your cities.
They're still good for freshly captured cities you want to hold though.
They can upgrade to a War Elephant.
How about using elephants to clear forests, and jungles?
(that's what they've been used for in real life for hundreds of years)
Or you could just give Elephants the ability to Clear Forest & Clear Jungle with a workrate of 900%. I know I would want to capture a couple then
@charleswatkins: You need the Large Animal Stable, and Ivory, to upgrade the Elephant to a War Elephant. Or a Tesseract.![]()
