I think that it woudl be nice to be able to choose what one of you defenders defend. Sometimes you would rather sacrifice a conscript unit then lose one of your elite defenders. It ould have to be something that you could turn off if you wanted, ut it would be nice to have the option ot intercede and selecte a defender. Also maybe they could give one tyoe of unit say a sub or marine the option to attack selected defenders. For example special forces units often bypass the heavy defenders and stick and convouys and such.
