Depends on where the site is, and what we're going to have to defend against/clear out. Given that the johnson's men aren't going to get there that quickly, it stands to reason that we arn't going be be twiddling our thumbs while they get there. the machine guns were for the ogodgettingswarmedbyghouls/gangers scenario, so I'd say wait and see what the spirits turn up, then tailor what we get, for example, big open spaces, use barrier foam to set up baricade, pour on firepower till attackers are soup, confined corridors, get chemsuits and gasmasks, fill place with warp and lay down some knee hight monowire. Entirely depends on how heavy/psychotic our attack/defence needs to be.
