simulate splash damage?

[dmatsch]

I'm sure everyone's been hindered by the fact you have to score direct hits to kill vehicles.

 

A M82 hit 100' from a fuel truck should flip it on it's side, let alone disable it or kill it.

 

Does anyone have any ideas for simulating splash damage, either from script or within the vanilla mission editor?

 

I know about the trick to add an invisible infantry, and when he's dead, explode the unit -- How about on a moving convoy?

 

Thanks for any help
