12 x 24 Tile : What backer board can hold the weight?

on

Good day all. Getting ready to tile the walls surrounding a tub. We have 12 x 24 tiles, I currently have the walls opened up down to the studs. Do I have to go with cement board on the walls, or would a greenboard or something like that be strong enough? I plan to use aqua defense or red guard on the walls before tiling. I have seen multiple people on youtube saying you can use almost anything if you paint the waterproof membrane on it, but they are referring to water penetration, not strength (i think). These tiles seem incredibly heavy, so I am looking for some reassurance they won’t come off the wall and kill us.
