I take it from the faq for the rulebook that if it just says within then it counts. The FAQ is bellow.
Can you let me know if I am missing something here as the linbreaker rule just says within on the rulebook.
If a rule says it affects units/models that are 'wholly within' then it only applies if the entire unit/model is within. If it just says 'within', however, then it applies so long as any part of the unit/model is within.
