Say I only have a one strength infantry. It cannot be used as lead and on a wide attack the player wins 4-0. The defender losses are then 6 (with two attack leading units on the wide attack).
Obviously the infantry is eliminated, but now do I take 6 points off the morale track or only 1 as that is the infantry units strength that was eliminated?
No; you lose 1 morale, because you lost 1 strength point in the attack.
2) I ask only because another scenario which was cleared up on the forums is if units have to retreat but they have no legal place to retreat they get eliminated. Then the total strength of those units is removed from the morale track, not the losses stipulated by the retreat rules.
Those losses are stipulated by the retreat rules!
3) The Attacker losses say
"Add one point for each defense leading
Do defense leading units include counter attack units?
No, counterattacking units are not leading units.
