To Hit as normal, and resolve those hits, one at a time, first against
squadron models in base contact, then against models further
away, once the closest model is destroyed, just like normal.
To do this, allocate individual
hits, rather than individual·Wounds, one at a time,
to the closest·model in the squadron. Then roll for
Armour Penetration against the correct faCi ng (so ·against
the rear armour in close combat) and determine the result
of any glancing or penetrating hits. When this has been
done, resolve the next hit, and so on, until all hits have been
allocated and resolved.
