Rank above head

I am trying to make a rank system and I want to draw the army rank symbols above an NPC’s head. Does anyone know which functions that I should use and / or where I could get such symbols? Thanks

Make materials for them like I did, then you can hook it to HUDPaint and find a position relative to the player’s position to place it: (pl:GetPos()+Vector(0,0,80)):ToScreen() is what I use.
