Clarification Rule needed on Rule 14.35

[Blackcloud6]

14.35 reads: Demoralized units in an assault hex that fail a morale check must exit the hex, and may move only one hex when doing so (12.13). On later activations they flee at their full movement rate if they fail to recover.

So if I have an assault hex with a Soviet tank and only a demoralized German 1 step infantry (which is marked fired/moved) and the Russian fires artillery into the assault hex and the demoralized German infantry fails the resulting Morale Check by just one, a disruption result, it is not eliminated because it did not fail with a demoralization, but it did fail, is it then moved one hex?  If so, who moves it and does the Russian tank get a fee shot?
