These elite soldiers seem somewhat slow in terms of movement speed and combat reactions, but players should still listen out for the heavy clank of the suit as they move as well as the winding up sound of the chaingun. The soldier will sometimes (after a successful attack has been landed) stomp his foot down, followed by a distinctive 'ka-chak' as he prepares to launch a rocket at you. This makes the use of Hayden's shield imperative in defeating them.
