About this creation
This is the first in a series of Mech’s, or as I call them, GP’s “Ground Pounders”. I’ve been working on this project for awhile now and so glad to finally get it out there! The theme I have is based in WW2 and rooted out of Detroit Michigan! I plan on running with this theme with three other GP’s in the shop! I hope you enjoy this project as I know I sure am! Thanks for looking!

Back Story
John Cooper “Cooper Works”
A Detroit native, John spent the first part of his life working in and around the automotive industry. John always had a passion for Cars and aircraft, and after the great depression started his own company called Cooper Works. His business specialized in developing new components for the automotive and aircraft industries. His company soon was working closely with Garr Wood and James Doolittle, both speed demons, Garr with powerboats and James with seaplanes. John help developed new components to give these two an edge over their racing competitors.
At a chance meeting with Doolittle, he met Howard Hughes, and after some short conversation, they realize how much they thought alike! They soon developed a great working relationship. Howard often came to John to help develop and build key components to his aircraft designs.
During one visit to LA while having launch with Howard, Howard discusses a radically new concept for the Army. He called them “Ground Pounders” or GP’s. Howard talked about tanks and jeeps with no tracks or wheels, but rather legs and feet! John and his curiosity ask Howard to sketch up his ideas on a napkin. John asked him does he have plans to build these. Howard said no, not anytime soon, aircraft are my thing now!
A few years past when WWII hit America! John while going through his desk came upon Howards sketch’s of the Ground Pounders. Wanting to do his part for the war, John encouraged Howard on building the GP’s, and offered to help anyway he could. Again Howard said no and that he needed to concentrate on aircraft, but if you think you’re up to taking on the project entirely, maybe we could work something out. It didn’t take long before John had Howard’s support, and had his shop cleared out for his first full scale project. The GP’s!!

Quoting TF Twitch I like the WWII theme that you have here since it gives it an advanced yet primitive feel. Very nicely done. I do believe that it gives a new meaning to the term "walking tank."
