Despite reading these forums a lot, I still don't know how tactical combat works when squads are involved.

With single man units it's really straightforward. Roll attack, roll defense. Deduct defense roll from attack roll and reduce leftover from hitpoints.

With squads, what's the calculation? From the 1.07 update notes, I gather that members of a squad attack individually. Well what about defense? Is one of these guesses accurate:

1) Attacking squad rolls attack rolls for each of it's members. Each uses total attack divided by the maximum figures in the unit. Their results are added together. Defending squad rolls a single defend roll. Defense deducted from sum of attacks and reduce leftover from hitpoints.

2) Attacking squad rolls as in option 1. Defending squad rolls defense in a similar way, individually and then calculating together.

3) First member of attacking squad rolls his attack. A defense roll is rolled for total defense of the unit. Defense deducted from attack and hitpoints are reduced. Process repeated for every member of attacking squad.

4) Attacks rolled as per 3. Defense rolls are made according to individual defenses, not total unit defense. If a defender is killed, individual defense for next unit is rolled and reduced from remaining damage. Repeat the damage dealing for each defender as long as there is damage left.

There are countless of more variations, but these seem most likely. MoM of course used option 4, along with a bell curve for rolls.
