Civ 6 (Including RF and GS): Representations of Line Infantry

[Lonecat Nekophrodite]

What are the Civ 6 Units (Vanilla, Rise & Fall, and The Gathering Storm) represents Line Infantry of The Enlightenment Era most accurately (While french Imperial Guard and eng Red Coats ARE Line Infantry, and Caroleans in GS are graphically made as such) I don't know if other nations in game did have any?
What represents Line Infantry better?
1. Musketmen
2. Pike & Shot
