This student guide, one of a series of correspondence training courses designed to improve the job performance of members of the Marine Corps, deals with the skills needed by basic engineer equipment mechanics. Addressed in the four individual units of the course are the following topics: mechanics and their tools (mechanics, hand tools, and power tools and precision measuring instruments); gasoline and diesel engines; power trains; and auxiliary equipment (hydraulic systems, and vehicle frames). Appendixes to the guide contain information on the job duties of basic engineer equipment mechanics, preventive maintenance, and safety. In a separate section following the appendixes are four review units corresponding to the four lessons of the guide. Each unit contains a reading assignment, a lesson objective statement, and a written assignment consisting of a series of study questions for that unit. (MN)
