Walker Gear

During 1984, several types of combat mecha were developed and used by Diamond Dogs in their operations.

Design
Though in some ways similar to later Metal Gears, they were smaller and designed to accommodate a single exposed human pilot. ==Types=-
 * One with a moving electronic "headpiece", this version had no armor to protect the pilot and an extendable "arm" fitted with an assault rifle.
 * One with an armor plating with a viewing slot to protect the pilot from the front, armed with a heavy machine gun in front.

Behind the scenes
These mechs were first seen in the E3 2013 trailer, and later in the first Metal Gear Online 3 trailer. They resemble the later Metal Gear Mark 2.
