The High Mobility Material Handler (HMMH) is a variant of the Unimog Model 406/419 Engineering Vehicles. Except for its material handling equipment, it is the same vehicle as the Small Emplacement Excavator (SEE).
Originally called the High Mobility Material Handling Equipment (HMMHE), the HMMH variant consists of the same basic Unimog Model 419 tractor as the SEE, but in place of the front loader, backhoe and other tools and equipment of the SEE, the HMMH has a 4000 lb. capacity forklift, 6000 lb. capacity crane and 350 lb.-ft torque impact wrench as well as a suspension lockout system to retract the front suspension for forklift and crane operations. In field tests, the Unimog HMMH equipped with forklift/crane was determined to significantly enhance handling capability for ammunition, rations and material at Ammunition Supply Points and Forward Area Support Terminals.
The High Mobility Material Handler (HMMH) is identified by NSN 2420-01-205-8636 (Tractor, Wheeled, 4x4 DED) and by Model FLU10344. The HMMH is called Model 419.103 by Unimog. Manuals for the HMMH are shared volumes with the Small Emplacement Excavator, numbered TM 5-2420-224-xx where the xx represents the maintenance level..
