The YMS-07B-0 Prototype Gouf (Tactical Demonstrator) was a test unit based on the YMS-07A model. One unit was produced, the blue model 8127. The YMS-07B-0 tested the internalized armaments later seen in the production model MS-07B. This was accomplished by swapping out the forearms and using drum-type forearm modules based on the older MW-01 Mobile Worker Early Type and Late Type. These swappable forearm modules included a left arm-mounted 3-barrel machine gun and a right arm-mounted heat rod. The YMS-07B-0 was also capable of mounting the drum-type forearms used by the Mobile Workers.
