Lots of travel. One of the most traveled trades.
Sort of diverse. Your role is moving 'stuff' around, mostly by air. You might plan that work, do that work, do it at a large air base, do it from a non air movements base with less resources, do some surface transport. You'll get trained on aircraft loading systems, large forklifts, aircraft loading vehicles and equipment. You'll be trained in how to calculate (safely) how to load an aircraft once you get to a certain level.
Generally, it's a good Trade with loads of potential and loads of travel. However, because you provide a service to lots of customers (including the Army and the Navy), you can catch some abuse and often for things that aren't your fault (aircraft breaking down etc).
