A unit is in combat against two units BOTH with rear support, (say all are small units)
is it each attacker gets an additional dice, (each 7 dice) ?
does the defender lose 1 or 2 dice?
is it 14 dice versus 4 dice in the end?

Each attacking unit gains one die and the defender loses one die in total. So it's 14 vs 5.

correct!
