I tried to recreate a mobile suit from M-MSV using the GM Striker.
The "RGM-79F Desert GM" is a GM designed for desert areas that appeared in M-MSV. It seems to be a modified version of the Ground Type GM, also from M-MSV.
It has reactive armor in various places and is related to the GM Striker, so I used the HG GM Striker as a base.
I modified the form somewhat, attaching the arms higher and adding a roll axis to the ankles, etc. I think it now has a more natural standing pose.
The base is the HG GM Striker.
