MOS 63H Track Vehicle Repairer
The track vehicle repairer supervises and performs direct support and general support (DS/GS) maintenance on track vehicles; supervises maintenance on wheeled vehicles, material handling equipment (MHE), and chemical quartermaster equipment (less office machines); and supervises related activities including fuel and electrical system repair and maintenance. Duties for 63H at each skill level are:
a. Major duties.
(1) MOSC 63H1O. Performs repair of gas turbine power plants/ packs, diesel power plants/packs, compression ignition engine fuel systems, compression ignition air induction systems, vehicle air cooling systems, vehicle liquid cooling systems, track hull electrical systems, automatic transmission assemblies, track vehicle cross drive transmission assemblies, transfer assemblies, hydraulic brake systems, mechanical/hydraulic steering systems, track vehicle hydraulic assemblies, fire extinguisher/suppression systems. Repair track vehicle using battlefield damage assessment and repair (BDAR).
(2) MOSC 63H2O. Performs duties in preceding skill level, supervises lower grade soldiers and provides technical guidance to the soldiers in the accomplishment of their duties.
(3) MOSC 63H3O. Performs duties in preceding skill levels, perform and supervise fuel and electrical systems repairer (MOS 63G) duties, performs and supervises wheel vehicle repairer (MOS 63W) duties, supervises lower grade soldiers and provides technical guidance to the soldiers in the accomplishment of their duties. Supervise and repair of fuel systems, fuel system components, electrical systems, electrical system components, turbine engines, diesel engines, cooling systems, transmissions, brake systems, steering systems, hydraulic systems, auxiliary drives, and personnel heaters. Inspects and troubleshoots tracked vehicle automotive systems, wheel vehicles and classify equipment.
(4) MOSC 63H4O. Performs duties in preceding skill levels, supervises lower grade soldiers and provides technical guidance to the soldiers in the accomplishment of their duties. Supervises the inspection and troubleshooting of tracked vehicle automotive systems and wheeled vehicles. Manages battlefield damage assessment and repair.
