There's about 50 people, in game, that have the skills to figure out that kind of distance and trajectory....... It would never happen. 
I'm thinking that using a spotter plane would alleviate the problem of determining the range. Said spotter merely
calls "mark" when he's directly over the town. The ground vehicles then form up around the lead GV,
all pointing their snouts at the town, and presto, rocket barrage.
I'd posted in the "Help" area of the BBS when I couldn't figure out how to fire the rockets on
the SdKfz 251. I got my answer along with this caveat, which I've not yet tried. If you select
to carry vehicle supplies on it, you can, per the post, rearm and fire another salvo. Hell, if that
does work, and it only takes a single vehicle supply to do that, one might be able to launch
-10- salvos per vehicle at a town...
The more I think about this, the more I like it. Think of ten or twenty of these things, firing
rockets, reloading, firing again, and again , and...well, you get the idea. I need to
try this out.
