WARMACHINE CITY FIGHTING

Wikipedia tells me the following about Urban Warfare:

Fighting in an urban landscape can offer some advantages to a weaker defending force or to guerrilla fighters. The attacking army must account for three-dimensions more often than two, and consequently expend greater amounts of manpower in order to secure a myriad of structures, ferroconcrete structures will be ruined by heavy bombardment, but it is very difficult to totally demolish such a building when it is well defended), and mountains of rubble. Examples, of this type of problem for the attacking forces include the fighting for the Red October Steel Factory during the Battle of Stalingrad, and despite heavy bombardment with artillery at point blank range (with some pieces large as 203mm howitzers), Soviet forces had to fight room by room to capture the Reichstag in 1945. It is also difficult to destroy underground or heavily fortified structures such as bunkers and utility tunnels. For example during the Battle of Budapest in 1944 fighting broke out in the sewers, as both Axis and Soviet troops used them for troops movement.

In an Iron Kingdoms setting, the same applies. As Remix explains, structures made of different materials can be easier or harder to damage during a game. There are rules that allow us to play games where models can move through and hide within structures during combat. Artillery (which is more and more available to every faction) can be used to bomb out structures and rain down indirect fire on troops without the need of direct contact. Also, the elevation rules allow us to carry out combat between forces on and in buildings, making for very cool games of WARMACHINE.
