The Spartans' main fighting force was their infantry. So It matches more with the Army than the Marine Corps would be my opinion. Doesn't mean the Marine Corps isn't this shiz, they just didn't have one. They had a naval fleet i suppose...
Spartans would kick some marine ass. No offense, but I think the marines would be scared to go to war with sparta, especially if their empire had survived to this day and time and they had guns.
Spartans r so overated... Samurais could totally kick their butts
Oh hell nah
