thanx for this island, i sightsee it and it is good addon for all police-like missions
big urban area made with some urbanistic mind, i just have to mark some places where there should be firestation, police station, school etc. cause city hall, hospital are placed good way with some area, parking around so it can be used for police missions :]
cause orginal Chernarus cities are not designed to such missions (they lack of thinking about infrastructure of city, they are "forest of houses" )
i don't know if you thought about non-military using island when planning it but really good addon and light (high FPS on my old PC, so it is not heavy as some other islands)
now i only must find time to finally make some missions, such island was the thing i missed
if you need some objects like you said above, maybe i could help you ?
in OFP i made some islands with my own buildings, objects, but it was easy WRP TOOL, now Visitor is pain

so i could make some buildings if you want, cause it would be good to have urban fights terrain (with real urbanistic plan which means: place for government, place for school, playground, city hall, shoping center, police station, firefighters station, bus station etc. )
and this small island with city only could do the job (maybe some few trees around to make "visible" terrain around it)
cause others' (of course also super) addons are not that light for my old poor 2006's PC like this one
the only problem in making own building is that we do not know how to make Arma2 destruction , but for police and R.P.G. missions it could be good
