Walker Gear/D-Walker from "MGSV: The Phantom pain"

Walker Gears were bipedal, small arm equipped, manned vehicles that were developed by Huey Emmerich in 1984.

These mechs saw limited use by the Soviet military in Afghanistan, several private military/mercenary forces in Africa (which had been supplied to them via XOF/Cipher), and Diamond Dogs.

They had originally been developed to ensure the Soviets won their invasion of Afghanistan and possibly the Cold War
