While they are still not official and might change prior to release (and will almost certainly be only optional rules even when the do), it might be worth mentioning that the AC/2 is actually a pretty decent anti-infantry weapon if you are using the BSP Asset rules to represent infantry. Any hit at all clears the damage threshold for the destruction check, and the AC/2 does it economically (by BV and cost, if not by weight) and at great range.
