@marcus711 The hang up with that is that all hits must be accounted for. If you attack with 4 fighters against a defending stack of 6 infantry, you will (statistically) land 2 hits (3/6 x 4 = 2), killing 2 of the 6 infantry. And then the 6 infantry get their defending rolls (statistically) getting 2 hits as well (2/6 x 6 = 2), killing 2 fighters. You would trade 6 enemy IPCs (infantry cost x 2) for 20 of your IPCs (fighter cost of 10 IPCs x 2). I wouldn’t call that a good trade.
