Mobile Field Force


The Lafayette Police Department Mobile Field Force (MFF) was formed in 1999. A civil disturbance at Purdue University following the victory of the women's basketball team in the NCAA tournament brought to light the necessity for a more modern, well equipped team that could deal with similar situations in Lafayette and surrounding jurisdictions.


The objective of the MFF is to function as a cohesive unit and adapt to constantly evolving situations within disturbances by using minimal or no force to resolve the issue. MFF trains and is prepared to handle many situation including, but not limited to:

  • Correctional institution issues
  • Labor disputes
  • Legal demonstrations
  • Passive/active resistor protests
  • Riots
  • Sporting event celebrations

The MFF can also be utilized for missing person searches, perimeter security for SWAT team operations, and assistance to EMS and Lafayette Fire for Hazardous Material incidents. MFF members also help make up the IDHS District 4 Homeland Security Task Force.
