Horizon Zero Dawn has 23 Grazer training dummies in the Nora region. Finding all their locations unlocks the trophy "Downed 23 Grazer dummies".
They look like deer made of straw, with a bow training target on them. You can knock them over with your spear. They are usually near campfires. All of them are at named map locations. Mostly at towns / settlements and two bandit camps. Nora Region is the snowy starting area, including the north-eastern snowy parts. This region ends where the desert starts.
