Do you mean AD0 and AD1 ? If yes those are off map units and they are accessing unit 154 in the Austrian OOB. It looks like the name was changed since the scenario was built but that won't affect how they work. I tried them and they work properly

If yes these are the same units you are referring to how did you determine they are at hexes 1,1 and 1,2 ?
