Noun (ancient Roman military term): a battle tactic in which a squad of soldiers close ranks into a tight square and link their shields over their heads and at their sides all around, creating a nearly impenetrable formation which can advance and engage enemy positions at close range without taking heavy casualties.
During the battle at the Moon Gate in Alexandria, Caesar ordered the deployment of the tortoise formation to neutralize the enemy ballistas.
