So, in the reload animation video i noticed that when the character was aiming there was some sway. Assuming there are houses in the first version of the game, I think you should be able to break a window and rest your weapon on the bottom of the window. The same should be possible for logs. by doing this your weapon sway would be reduced by x% This would give an advantage to defenders other than already defending and also give people a reason to take cover behind a log and not just run away like cowards.
