The Mesan Planetary Peaceforce, or MPP, was a military security force on the planet Mesa. The main reason for its existence was to respond to threats of seccy or slave unrest before they turned into genuine rebellion. It was the most heavily armed of the three Mesan paramilitary security units, followed by the Mesan Internal Security Directorate and the Office of Public Safety. Its senior uniformed officer in 1922 PD was General Caspar Alpina, who, under the Mesan constitution, answered directly to CEO Ward. (CS3)
