Its fine for the hill to be taken by any means necessary. But clean up your mess at least, if you use nuclear weaponry for instance decontaminate the hill before letting someone else have to deal with it. And strictly speaking the hill should always be status quo for each post, that way this doesn't turn into a roleplay of sorts with people always trying to outgun each other. I don't expect the grass to stay green all the time, there's gonna be battle damage. In any case, the hill is mine.
