This is a typical guard of the city Stormwind in the game World of Warcraft.
I put the model together in the app Wow Model Viewer, and exported it as an .fbx that I imported in to Blender. Then I added a new VRM compatible armature that is Mixamo friendly. See the "salute" animation from Mixamo in this youtube video: https://youtu.be/fnecxv5fhIM
