Assault Shield Trooper

From Wikitroid, the Metroid wiki

Assault Shield Troopers represent the best of the Shield Troopers in the Space Pirate military. They are equipped with Missile-resistant armor, a portable battle shield, and upgraded weaponry. Rather curiously, when the Grapple Voltage is used on them their armor will break off. It is possible that their armor has a limited amount of energy, like Samus' own, but they can fight without it.
