To protect against rain scutum – a Roman shield – was hidden during the march in a special cover with goatskin or cowhide. For convenience, the scutum was worn while marching by hanging it over the shoulder or on the back with an attached strap.
The shield was strong enough to effectively protect legionnaires from archery and blows, and light enough to be carried over long distances. Scutum was usually made of oak or birch.
