You have asked for information on the EQUIPMENT OPERATOR rating. The rating symbol is a Bulldozer
The U.S. Navy is made up of four distinct groups of technical rating specialist. These categories are:
Administrative and Medical
Aviation
Hull
Construction
The term SEABEE was originally coined to define the Naval combat construction forces assigned to the Naval Civil Engineering Corps, and the SEABEES became a recognized organization in 1942. The traditional SEABEE specialty ratings are made up of seven classifications shown as the top left seven on the home page. As SEABEES tend to be self sufficient in a combat zone or other deployed area, other ratings are assigned to the SEABEES to provide the skills necessary to accomplish this.
While any rating within the U.S. Navy can be billeted with a SEABEE group depending upon the nature of the task at hand, the home page includes thirteen typical other ratings that were most assigned to be part of a SEABEE unit during the Vietnam Era.
Equipment Operator (EO):
EOs work with heavy machinery such as bulldozers, power shovels, pile drivers, rollers and graders. EOs use this machinery to dig ditches; excavate for building foundations; break up old concrete or asphalt paving and pour new paving; loosen soil and grade it; dig out tree trunks and rocks; remove debris from construction sites; raise girders; and move and set in place other pieces of equipment or materials needed for the job.
