The rule of "within"?

[World Of Pain]

There are numerous rules in BRB and Codex´s that state in a different situation to something to be "within" of something. In situations like deployment, embarking, disembarking, shooting, "who can fight" and many others there is a clear wording and/or picture to tell us how this rule is suposed to be understod. But even in these rules it is not allways the same. Some of the rules like deployment clearly state that models must be totaly "within" players deployment zone but in "Line breaker" it states that as long as you have one model completely within it is enough. Also in shooting and "who can fight" situations models need not to be totaly within of range or distance for players to be able to use them.

So there are different variations of this. How do you play this rule when there is no clarification of anykind available? Like Tactical objectives 42 and 43? Or rule when you hold your objective?

1) Is it enough that some part of one model´s base is within?
2) Or does it require to whole base of one model from the unit to be within?
3) Or does whole unit need to be within?

What do you think?

If any part of a model (or it's base if it has one) is within the range then it is within.

You always measure from the closest part to the closest part.

For example, if any part of a model's base is within 6" of the base of an enemy model, the two models are said to be within 6" of each other

Good call! Just got confused because of all those variations of this rule. But like you wrote; there is a rule for it if no clarification exisist´s.
