    From the dereference, of sn_7, obviously.

Sorry: I meant why that variable?  What does the dereference have to do
with Utn?

The dereference is to a field inside Unit_Table, not Utn.  If it's just
picking some random integer, why not pick T1, T2, T3, or T4, which I
added just to make that happen.
