Loadmasters & Flight Mechs usually wear 2 stripes.
I knew a ground ops guy in DXB who was runnin around the place wearing 4 stripes; couldn't help asking the pratt wtf he was up to. Well, he was working ground dispatch (stapling flight plan together, calling crew out etc...) and acting as loadmaster (actually added a fuel figure to a transit loadsheet) so he was working two jobs @ two stripes each. He was serious about it too.
