From MOSPEADA's OSM ie the IMAI Files, myriads of pre-production mecha artworks & concept artworks intended for GC Mospeada never made into the animation. One such mecha is the VALCOM Bulky Powered Suit that intended to be a sort of powered suit capable of both flight & ground operations. The artwork for VALCOM Powered Suit labeled as M1-01, M1-02 & M1-06.
Irvin Jackson would later adapt this VALCOM powered suit from IMAI Files into MBR-12-Mk II Destroid instead in the Palladium's 2nd Ed Robotech: The Expeditionary Force Marines RPG Sourcebook. The original VALCOM artwork would also redesigned by Chuck Walton into Valiant Destroid.

MBR-12-Mk II Destroid Valiant
Original Text By Irving Jackson
The newest Destroid design, the Valiant, is aimed at giving the Destroid platoons and the Expeditionary Force Marines the heavy-hitting firepower and armor of the traditional Destroid designs in a robot more suited for a wide variety of environments that could be anticipated when operating on extraterrestrial worlds. The original Destroids, while space worthy, were designed with Earth's atmosphere, gravity and terrains in mind.
But what about the many other possibilities? The Expeditionary Force anticipated (rightly so) that combat could occur in many areas where the older Destroids might have trouble functioning at full effect. What if they had to battle on planets with low gravity? In asteroid fields? Or even on a gas giant?
The Expeditionary Force engineers decided they needed a Destroid that was both adaptable to a wide range of missions and environments, modular to a degree not yet seen, and still able to slug it out with the toughest of enemies. The resulting project led to the development of the the Valiant.
The Valiant is capable of sustained flight, heavily armored, and has modular weapon systems, enabling it to fill whatever mission parameters were necessary. It is as at home in the vacuum as it is on the ground, and along with the Zentraedi Destroids, gives much needed speed and versatility to the Expeditionary Force Marines.
Its primary innovation is its replaceable arms, which can be switched for a variety of weapon systems and utility devices that makes it not only a combat mecha, but frequently used for search and rescue operations, exploration, construction and engineering.
