Yes, it would probably have been a combat support role given the technological level of that time. Let's presuppose that it is in that role that any of the combatants of WW2 had been able to utilize it properly. Even this role, a chopper of some sort would have improved immeasurably the logistical operations of, for instance, the early stages of almost any campaign in World War 2.
Also I have to add this, I belatedly realized that a chopper of this level wouldn't be as effective as I envisioned in the first place. Even today's hi-tech combat equipment and vehicles still have problems with sand.
