Imagine that you are a ladder company officer at a fire in a private dwelling. The fire is on the first floor. You and your inside team are moving in with the engine. Your outside team is venting from the exterior. Over the radio, you hear one of the team announce, "there is a big dog in the back yard. It bit me. Watch yourselves."
Does "You and your inside team are moving in with the engine" mean "You and your inside team are stepping in/intevening using the fire engine"?
I don't remember hearing that usage when I was a firefighter, but I imagine the engine is short for "the engine company". Both the ladder team and the engine team are moving into the building.
