In the section describing how BAR effects critical hit chance of support vehicles, the 5th paragraph in italics gives an example of armor piercing rounds damaging a support vehicle that confuses me:
If, on the other hand, the Support Vehicle were struck by
an AC/5 using armor-piercing rounds, the vehicle would be
treated as if it had a BAR of 4 (7 / 2 = 3.5, rounding up to
4) rather than 7 for purposes of determining penetrating
critical hits. Both hits might do critical damage because the
autocannon’s damage points exceed the unit’s effective BAR,
even though together the two autocannon hits would only
eliminate 10 of the Support Vehicle’s 12 armor points.
(from page 207 of the Total Warfare, corrected 3rd printing PDF from the BattleCorps online store.)
The bolded part is what confuses me - why is the BAR divided by two? The rules for armor piercing rounds on pages 206 and 140 state that a support vehicle with a BAR of less than 10 should have a +2 modifier when rolling on the vehicle critical hits table. I can't seem to find any reference to dividing the effective BAR; is the example in error, or am I just failing to find the correct rules page in the book?
Thanks!
