The resolution is much greater than steps. It's more like strength points and you can lose 0.1 of a strength point, each of which correponds to a portion of the unit TO&E, so you're not losing a third or a quarter of a unit each time you take losses necessarily, but you can still lose an entire unit in one battle.
