Since you can never select that you want to shoot an Assault weapon or a Pistol, you can't fire it. His argument was now as follows: Since the rules regarding the shooting phase disallow you from even selecting a unit that Advanced or Fell Back, you never get to section 2., which tasks you with selecting a weapon. You may not pick a unit that Advanced or Fell Back this turn, or a unit that is within 1' of an enemy unit. First, you must pick one of your units to shoot with. Choose Unit to Shoot with states the following: Likewise the section regarding pistols states the following:ДЄ model can fire a pistol even if there are enemy units within 1' of its own unit, but it must target the closest enemy unit. If it does so, you must subtract 1 from any hit rolls made when firing that weapon this turn. The section regarding assault weapons states the following:ДЄ model with an Assault weapon can fire even if it Advanced earlier that turn. A unit that Advances can't shoot or charge later that turn. Roll a dice and add the result to the Move characteristics of all models in the unit for that Movement phase. When you pick a unit to move in the Movement phase, you can declare that it will Advance. The Basic Rule Book for 8th Edition contains the following phrase regarding 'Advancing': He did not mean 'useless' as in 'not as good as other options', but as 'the rules as written mean they don't give any advantage'. I recently got into a discussion with somebody, as they tried to explain to me that both Assault weapons and Pistols were actually completely useless in 8th edition.
