Yes, but if the sheath is metallic, how is it different than armour? They are both metallic and they are both sourrounding the cable.

True, but usually armour provides physical protection against damage (to some extent at least). I'd suggest that the sheath is just the outermost layer of the cable (other than basic insulation). It's all a matter of degree though - given a nail gun or a JCB, the performance of armour over a soft metal sheath isn't that different.

Armouring provides additional protection against damage to a cable than a sheath does.
