it was a fortress on the way to whatever bumfucknowhere town. and once they make it there, the coast is in himars range and they can disrupt travel along that route. and if they simultaneously destroy the crimean bridge and drone the black sea fleet (specifically transports) crimea has no travel links left and is open for attack. that was the plan, but the plan was retarded. too many variables to begin with, and of the 3 sub objectives objectives they achieved zero(0). and of course on the other end, taking robotown is a symbolic victory in that the only gains from ukranian kanterhruk have been nullified.
