Massive Special Task Force 1, also code-named "Flesh Wall", was a disbanded task force consisting of two merged Mobile Task Forces: MTF RG-1, and MTF RD. This group, consisting of Battalions, instead of Teams, was the final resort of Equestria to stop the Changelings in Incident 005COB-1 (Also known as the Changeling War). Thankfully, it did help. The Task force was then disbanded, but it can be reformed by the P4 Council again in case of an attack by an enemy army.
