1st Panzergrenadier Regiment Equestria

The First Panzergrenadier Regiment Equestria ((abbreviated 1. PzGren.Div EQ)), aka First Panzergrenadier Regiment Leibstandarte Princess Luna ((abbreviated 1. PzGren.Div. LPL)) was Princess Luna's personal bodyguard. Initially the size of a battalion (300 personnel), the LPL eventually grew into an elite regiment-sized unit. The term Leibstandarte was derived partly from Leibgarde – a somewhat archaic Germane translation of "Garde du Corps" or personal bodyguard of a military leader ("Leib" = lit. "body, torso") – and Standarte: the [REDACTED] or [REDACTED] term for a regiment-sized unit.
The LPL independently participated in combat during the Boxer Rebellion, and was amalgamated into the Royal Equestrian Armed Forces (also transferred to the Night Corps) prior to the end of the Rebellion. By the end of the Boxer Rebellion it had been increased in size from a battalion to a Panzergrenadier regiment. The Kaiser, now surprised to see Equestria and its allies joining the war, has allowed the regiment to remain in Equestria all they like.
