31 Service Battalion is a unit from the Canadian Forces 31 Canadian Brigade Group, a unique element of the Canadian Forces, whose task is to augment Canada’s military by providing Combat Service Support soldiers.

31 Service Battalion is committed to achieving excellence in the following four Lines of Operation:

  1. Operational readiness to respond to a domestic operation within 24 hours when Canadians are in danger.
  2. Ability to operate effectively in Full Spectrum of Operations, especially a Warfighting environment.
  3. Provision of a high standard of Technical Services to all CAF dependencies in our area of responsibility.
  4. Strengthening the Battalion with a new regimental identity, strong succession plans, and recognition of outstanding soldiers.

31 Service Battalion has approximately 300 soldiers, both Regular Force and Reserve Force. The Battalion is organized into a Battalion HQ, a HQ Company, four Support Companies and a Technical Services Platoon. Battalion HQ, HQ Company, Technical Services Platoon and London Support Company are located primarily in London, with the other support companies in Windsor and Hamilton. The Battalion is made up of the former 21, 22 and 23 Service Battalion as well as parts of ASU London. 31 Service Battalion is one of the largest reserve units in all of Canada and has thrived in a time of great change and challenge. The greatest strength of the Battalion is the soldiers who do the dirty and dangerous work in difficult conditions both in Canada and around the globe.

31 Service Battalion's motto is "Bellum est Cras" which translates as "The War is Tomorrow"; a reflection of the Battalion's commitment to preparing for and conducting operations of any nature, anytime.
