The aerodynes come in a range of sizes, though all function the same. A reactor generates a high temperature/pressure volume of gas which is either vented directly out the back for forward thrust, the body is something of a lifting body shape (almost anything will "fly" with enough thrust) or vented through the side mixers to cool and add mass versus velocity for vertical thrust without too much a blasting effect. The EDF choose to use tracked combat vehicles almost exclusively while the ILR use wheeled types. Both use electric drive motors in the various wheels. In the EDF tracked units, that means there is no single drive sprocket for the tracks and they can still proceed without the tracks if needed.
