Units that do "*" damage plus backshots

[Crow]

I understand that units that do "*" damage, have a 50% chance of doing 0 or 1 damage. But what happens if that unit attacks another unit from behind. Does the "*" round up to one, or does it do * + 1 damage?

[Kastor]

0* can be reduced to 0 damage by a weapon hit critical. Thus I'd assume 0* gets a "by one step" damage upgrade on the 0 / 0* / 1 / 2 / 3 / 4 ... damage scale. So from the rear a 0* / 0* / 0 unit does 1 / 1 / 0* damage.

Attacking in the rear with a 0* attack does 0* + 1 damage.

If you're using SAR, roll once to hit and then a d6 4+ to see if it's one or two damage.
If you're using MAR, roll a separate pair for the 0* and for the 1.

I hadn't thought about it before but that's a very good question.

Attacking in the rear with a 0* attack does 0* + 1 damage.

If you're using MAR, roll a separate pair for the 0* and for the 1.

I believe this is the correct answer.
What makes this interesting to me me is this means that if you get behind a unit with
a Ferret VTOL you can get at least 1 damage on the unit if you hit and have a chance
of a second point.  With a dirt cheap unit that can move 30.

the legalese...
The +1 damage from rear is based on a "successful attack".  A successful attack is one that's attack roll ties or exceeds the target number.
You have to be capable of doing damage (there's a separate requirement listed, not a 0 stat at that range), but you don't need to roll the 0* and get 1.
