4th Edition DF chart - Opportunity Fire question

[waynebaumber]

Hmm, some interesting points made,
 I agree that only opp fire v  personnel units does not include trucks towing etc
 Trucks do get hit by DF  even though they have an armour value of  -1

 I used to also add a right shift if a truck was towing MTR, A/T gun etc but I can concede the argument against that.
