Delivering the appropriate products to the sites are another aspect of the Okinawa system's development that isn't connected to these events here. I was gonna make the trade aspect fairly simple with every char involved with the specific base bring one full load of each needed commodity and SS it's delivery. Considering the number of players with factions involved that should give thousands and thousands of the appropriate commodities where needed.
So if the DSE have any security/escort ships, these events are one of those times where they are guaranteed to be used. I believe a repair ship may be useful to if the pilot is good with one.
