Questions on 14.1, 14.5 and Wire

[fanghawk]

Getting back into PG has been great and I'm slowly wrapping my head around some of the nuances.  That said, I've come across three instances where I need a little clarification.  I tried searching through the forums but couldn't find these answers specifically.  I apologize if I missed them.

First, in 14.1, it says if a 12 is rolled, the unit or leader is automatically demoralized.  For the 12, is that modified, or unmodified, i.e., does it mean "boxcars" or does it mean a modified roll of 12?  Since rolling for morale on an M2 result means a 10 on the subsequent dice roll would be a 12...does that mean a 10 morale unit is automatically demoralized despite only failing by 2?

Second, in 14.5 it says that for morale checks and recovery rolls, no unit or leader may use an "adjusted morale value greater than 10 due to any combination of bonuses or circumstances."  Since it says "adjusted" does that mean leaders with a printed morale of 11 still get to use the 11?

Finally, since I've pulled out some "Invasion of Germany" scenarios, I was curious how 4th edition handles wire.  Short answer it doesn't really.  So I went back to Desert Rats, the last place I really saw it mentioned, and got the rules there.  One small glitch, though.  In Desert Rats, it says a foot unit must spend an entire turn in the hex to remove it.  It also says a tank can spend 3 MP in the hex to crush it and remove it.  All well and good except the 4th ed. TEC says, "may be removed by ENG".  So does that mean it has to be an ENG instead of any foot unit (and a tank still works) or is that meant to say that ONLY and ENG unit can remove it?

Thanks guys!
