well...this is just me, but there's this command, saveVar which saves a variable to work in all future campaign missions, works as so:
saveVar "variableName"
so, I suppose you could have a variable for the soldiers, like "jimmybobdead", and then do the old variable thing. And in the next mission you'd work with these variables when creating your team (for instance in the "condition of presence" space)
Right, just my suggestion. G'lucl (y)
