**Testudo** → It originates from Latin *testudo*, meaning a tortoise or a protective covering. The word refers to the shape of a tortoise shell, which was used metaphorically to describe a military formation that provided protection, resembling the shell of a tortoise.
Imagine a tortoise with its hard shell providing protection — that's how 'testudo' relates to a protective formation in battle.
