In a particularly ingenious idea to quickly protect their anti-aircraft assets while still providing direct support for their infantry, the Germans would place 2cm quad anti-aircraft guns on the roofs, attics, or the top floors of buildings.
This tactic allowed the guns to fire at Soviet aircraft as well as providing direct firepower against assaulting infantry.
By sand bagging and fortifying the house, the Flak Nest was protected against all but heavy calibre high explosives.
The Germans generally built their FlaK Nests in abandoned buildings, filling up the areas below and around the Flak Nest with rubble to prevent collapse, increase survivability and to limit entry. FlaK Nests are therefore open bunkers and not buildings and cannot be entered by any team.
You can either model your Flak Nest on the ground or on a single story building. In both cases it has a base size equal to an Artillery base. If it is destroyed it becomes a destroyed bunker and is Impassable terrain.
