This is an older project, but on the day the Military Police Zaku was released, I saw someone's work on X and wanted to try making one myself. I bought two sets of Kampfer arm parts, an Aerial modified torso and other parts, dug out some Geminass ground combat type parts that were sleeping in my home's cycle mountain, and mixed the usable parts to create it.

First, in normal mode (without riot control equipment), I transplanted parts to reinforce the armor of the arms and legs. The Military Police Zaku body and the Kampfer arms cannot be connected as is, so I made this to connect them. This is the riot control equipment. Hard rubber bullets
