The 'Behind Mykybe's Veil' Campaign has made a major right-hand turn, thanks to some spectacular cock-ups on my part, and the PCs are now intent on launching a full scale planetary assault on a planetful of Logicians. They have some advantages - the dynasty's founder was involved in the Meritech Wars, so they have some historical precedent, and they can call in the AdMech for assistance, something I suspect they would gleefully do anyway.
But apart from the planet having a native biosphere, and swarming with at least a dozen ships, they have no idea what to suspect.
The Logicians, of course, have been well dug in, and they're certainly have a well-protected station in geosynchronous orbit above their surface settlement ( I'll just borrow the stats for the one in Frozen Reaches for the latter) but what sort of defences, units, etc would the ground war forces have given their knowledge of orthodox and highly unorthodox tech? Void shields over the town, and a variety of Planetary Defense Lasers, seems likely.
The PCs are going to be made further unhappy when they discover the target is surrounded by miles of featureless flood plain with no better than knee-high cover.
Any and all suggestions welcome, as I suspect this brushfire war is going to come as a very rude shock to the players...
