Also a quick addendum based on my personal experiences with bolstering troop XP through the bonuses: this does not affect replacements. Replacing units during campaigns will draw from the national morale levels, from what I have seen. If this is incorrect I'm sure someone more knowledgeable will correct me.

The long and short of it is, all you can do is give the player a "boost" from the start, I think. Repairing a destroyed tank that started from 75 to 85 will probably re-roll on something from 55 to 70 depending on the exp/morale spread.
