[ASLML] DC residual

[rich domovic]

Can DC toting squad in a building next to a bridge (DASL hex dF2, bridge dE3), 
throw its DC onto the bridge when a close topped enemy AFV crosses the bridge 
as Defensive First Fire in order to place 12 residual on the bridge?
We thought that it could, the bridge is not affected as in wasn't a "set" DC, 
and the AFV wasn't affected as it was not the predesignated target. Did we do 
this correctly?
Thanks,
Rich
