35 Motor Transport
Marine Corps OccFld 35 is the motor transport field that keeps vehicles moving, maintained, and ready to support the rest of the force. It is one of the most visibly useful support communities in the Corps.
This field fits Marines who like vehicles, practical repetition, and work that stays close to the daily movement and support rhythm of a unit.
The field naturally splits into the maintenance side and the operator side. Both matter because movement readiness fails when either one falls behind. That makes 35 a good fit for Marines who want work that is practical, visible, and easy to explain in plain English.
