Battle Mammoth (and things)

Now that mounts are a thing, we can up the ante in mission difficulties and balancing it out by allowing combat oriented tames. Raising your own mammoth (limit of 1) and equipping it with tier 3/4 body armor (with spikes?) would be boss tier tames meant for the toughest prospects and bosses. Who knows what nasties is lurking out there ready to rear it's ugly heads in new biomes? For balance purposes, smaller creatures won't dare mess with the mammoth and the mammoth won't mess with them, keeping our precious wolves and bears the proper threat they are meant to be. Wolf tames instead of bears, workshop and tech tree would give us drones as alternatives to tames.
