What is the origin of the horse in the US?
Prehistoric horses began in America and moved into Europe and Africa via the Siberian land bridge. However the American horses died out during the Ice Age and there weren't horses in America again until the Europeans arrived.
if you're talking about a real horse than its called a roan but if your talking about the horse on the restaurant i don't know. You may be referring to the US Air Force "Red Horse" squadrons. It stands for "Rapid Engineer Deployable Heavy Operational Repair Squadron Engineers". These are construction units used to build air bases in combat zones.
