Great resource Ivan. Invaluable for the entire pre-HD radar phase.
FYI - While the Marauding Army has landed and crashed markers set up, it is also set as Unmanned, so cannot ever actually have a land/crash site. Same for Imperial Probe, Ground Attack, Search and Comm Waves. I'd assume Roving Bands cannot crash as well, having 1pt of damage capacity, so any damage destroys them. Didn't try to tractor them - not sure if they can be forcibly landed.
