MKs are trained not only as technicians, but as managers and leaders, acquiring a breadth of knowledge in all areas of machinery operation and maintenance from internal combustion engines (gas/diesel gas turbines) to environmental support systems (heating/ventilations/air conditioning), hydraulics, basic electricity, and areas of hazardous material recovery and control. In addition, MKs will learn to work on the Coast Guard's computers and computer-based programs. Many MKs are also called on to act as federal law enforcement officers. As one of the Coast Guard's largest ratings, Machinery Technician (MK) offers opportunities for assignment at every Coast Guard cutter, boat, and shore station."]
