Will the players have the ability to attack and destroy walls/buildings?

In "the olden days" towns/villages etc were walled in to protect the people. Someone was always there to guard and alert the other people of danger.

Protection of the area was thru the guards and the walls - but the walls could be burned or rammed to allow access to the area.

In this game our tribal areas will not always be "manned". Because of players play time, the time zone they are from and the size of the tribe - it will not always be possible to have 24/7 guards. Walls will help keep the inside area safe from invaders.
