Each Engineer Special Brigade (2nd, 3rd and 4th) had a Engineer Boat Maintenance Battalion. These specialized groups consisted of five units: three Engineer Maintenance Companies, one Engineer Heavy Equipment Shop Company, and one Engineer Parts Supply Platoon. For the 4th ESB we have yet to find what these units were; the 2nd and 3rd ESBs have these identified.
When we learn more about this 564th Engineer Boat Maintenance Battalion we will add it here.
