inspects his vehicle before, during, and after each operation and reports defects. The company com- mander makes regular inspections of his company's vehicles and causes appropriate adjustments beyond the capabilities and facilities of the company to be reported to the battalion commander (battalion mo- tor transport officer).
c. Second echelon maintenance. Second echelon maintenance is a regimental function which provides for preventive maintenance, minor repairs, unit re- placement, inspections, lubrication, supply, battle- field recovery, and evacuation. Within the regiment, there are two groups responsible for this mainte- nance. In each company, except rifle companies, there is a company automobile mechanic who is re- sponsible for maintenance of company vehicles, the battalion headquarters company automobile me- chanic being responsible for maintenance of the rifle company vehicles in his battalion. All work which cannot be performed by company mechanics is passed on to the regimental maintenance section. It is always advisable to have maintenance operations performed by the lowest echelon capable of perform-
ing the operation. d. Third, fourth, and fifth echelon
maintenance. This maintenance is normally per- formed by ordnance personnel. Vehicles requiring service maintenance are ordinarily reported to the supporting third echelon unit and immediate steps taken to have them evacuated for repair or replace- ment. In emergencies, the service company may have to perform some third echelon maintenance.
