Hi, I'm an Italian mapper who has drawn some military polygons... I think it's not correct to put access=private for these reasons: 1) apps like OSMAND allow you to use private roads; 2) military lands are off limits to everyone except authorized military personnel; 3) mapping and photographing objects in military lands is generally prohibited. Personally, if I know the geographic boundaries of landuse=military, I only draw these but not what is included inside (no roads, buildings, etc.). I also point out: 1) the boundaries of landuse=military are somewhat uncertain; 2) fences are not shown while gates on access roads like highways do not have the access tag.
