here is the "Tank Station" ground floor and roof layout. It contains a random crate spawn location, a record for the staff parts you have to collect, a part for the zombie shield on the roof that spawns here sometimes and the MP40 machine gun, a classic weapon from World At War and in any World War II game.
Watch out when on the roof as some people run blindly onto it and get squished by the giant robots walking past. Have a peek before venturing out or its squish goes the weazel :).
Here is the map layout below for this section:
