We just played a game last night and I was Russian and my friend Germany and he sniped Leningrad away from me with a clever maneuver that I didn’t see, but then he was kind of stranded behind my lines, so he couldn’t reinforce it easily, but I couldn’t take it back very soon either (I was two turns away, and my relief force was prolly a coin flip anyways), but he was saying that he wished he could just kill all the bases and then sail away lol.
Thankfully he couldn’t, but we were toying with a house rule.
We thought it’d be lame if a single inf could do it, but maybe if the total UV of all the units attempting to sack the assets was equal to or greater than the UV of the assets themselves (IC’s, AA guns, NB, AF etc…) then you could do it.
