Soldiers are the only friendly NPCs that use the Bolt-Action Rifle and can also use turrets at the base.Soldiers can only stay at the base(safe zone),so if you try to take a soldier on your adventure the soldier will eventually disapear and teleport back to their base.Soldiers are immune to melee damage from players(sense there freindly and cant do damage to your allies) but melee enemies can still damage them like werewolves and zombies.
This is not actually how they look(this is just for copyright reasons)
