Ибо там написано следующее:
This document provides rules updates for a wide selection of Forge World Tau Empire units previously covered in early Imperial Armour books.
Each unit entry indicates which Force Organisation Chart slot it may be selected as, which Codex this applies to, and the document as a whole bears the ‘Warhammer 40,000’ stamp. This stamp indicates that the units are intended to be used in ‘standard’ games of Warhammer 40,000, within the usual limitations of Codex selection and Force Organisation Charts. As with all our models these should be considered ‘official’, but owing to the fact that they may be unknown to your opponent, it’s best to make sure they are happy to play a game using Forge World models before you start.
Что как бы намекает, что теперь сии отряды - официальные отряды 40к, а не отряды ИА. То есть, по логике, их не имеют права запрещать на турнире, если даже ИА запрещен. Так ли это?
