Line of Sight
Posted: Mon May 06, 2013 11:37 am
So, a rules debate cropped up at NagoyaHammer between myself and another player. Before I get into the details of it, I want to briefly cover two very important points: RAW and RAI.
RAW means Rules as Written. It is a strict way to apply the rules. You follow the rules to the letter without inferring or implying anything.
RAI means Rules as Intended. It is a liberal way to apply the rules. You try to determine what the writers wanted a particular rule to do.
Both methods have merits and flaws. RAW works because it means that everyone is on the same page, but at the same time it only works if the writers and the English Language are infallible. RAW is responsible for such classics as players arguing that Combi-bolters could fire an infinite number of times in a turn back in the old 4th ed. Marine Codex and from the same book the fact that Marine Terminators did not actually have Terminator Armour.
RAI works because it tries to find the best way to play when the (often) contradictory rules don't work properly. However, it assumes that any given player knows what the writers wanted from the rules and results in many differences of opinion.
With that out of the way, let's get on with the matter at hand.
In a game at NagoyaHammer my Necrons were facing off against some assault marines and shot at them. In the marine's turn, they used their jump packs to jump over the necrons. In the assault phase they declared a charge against the necron unit and the claim was made that because the necrons were not looking at the assault marines, they couldn't fire overwatch.
This comes from the main rule book, Page 8, top of the second column.
"For one model to have line of sight to another, you must be able to trace a straight, unblocked line from it's eyes to any part of the target's body."
So, by RAW, you can only shoot at models you are directly facing/looking at.
Now, as things stood at the event, after a quick discussion I figured that the impact on the game wouldn't be that great and just went ahead and gave up my overwatch fire. End result the Necrons wiped the floor with the assault marines and went on to storm over to the objective and contest it. However, I can see this coming up again in the futre so I want to talk about it and find a solution that everyone is happy to work with.
The rest of page 8 gives some more information which I think should be added to the debate.
The last paragraph of the second column says "Firing models can always draw line of sight through their own unit just as if they were not there. This assumes that the soldiers shift their stances to open firing lanes in order to maximise their own squad's firepower." The second sentence is most relevant. There is an assumption written into the rules that the models are not as static as they might appear to be. Elsewhere on the same page it makes a point that the miniatures are plastic and resin and cannot therefore communicate with the players. (Also by strictest RAW at that point, Metal models cannot be used in the game).
On page 10 we get the following from the 'Turning and Facing' section: "...Whilst the direction a model is facing won't impact it's ability to shoot or charge into combat later in the turn, it's always better to have it facing towards the enemy, just as it would on a real battlefield."
on page 49 we get the following from the section 'Swooping Hunters': "...Flying Monstrous Creatures can shoot all around, just like other non-vehicle models."
Finally, in the vehicle section we get the following from the section on 'Vehicle Weapons and Line of Sight': "...On some models, it will actually be impossible to literally move the gun and point it towards the target because of the way the model is assembled or because the gun has been glued in place."
The vast majority of models don't have an option to change pose mid-game and applying the rule would result in some strange situations where models have to be positioned to fit in a space provided, but were assembled looking in a different direction (bike models being the obvious example). Strict RAW also means that Wraithguard, Wraithlords, Zoanthropes and Hive Guard can never fire any weapons as they don't actually have any eyes. The rule also results in some strange differences between units. E.g. Imperial Guard have very limited vision due to their helmets whilst Termagants which have eyes on the sides of their heads can probably claim to be able to see 270 degrees or more. It also raises the question of where the model's eyes are looking.
My own view on it is that non-vehicle models have a 360 degree line of sight and that the "measure from the eyes" rule simply tells us where on the model we should start from. E.g. you can't measure from the top of the model's banner pole. The rule book gives examples of models being unable to move due to the way they are assembled and makes allowances for that.
Anyway, there are the relevant sections of the rulebook laid out for you. There are threads on most of the major 40K forums discussing this and none of them can reach an absolute consensus. So, until GW gets around to providing an FAQ for this, lets work out our own answer.
Thoughts and comments below guys.
