Soldier villager

These villagers could be found spawning like wandering traders but you could hire them using emeralds the same way you tame dogs.they could pick up armor and gear the same way dogs do and will attack mobs using the same aggression logic as dogs. They can also spawn at special villager camps that have a 10-20% chance of spawning instead of abandoned camps.they would teleport to you if you’re more than 20 blocks away and can be interacted with once hired to give them orders like defending a 2x2,6x6,16x16 etc. area or walking in line if you have multiple (this could use the walking-in-line logic of lamas) .
