Welcome to Librarium Online!
For the 3 HQ choices (Warboss, Big Mek and Painboss), the Wartrukk entry states "X and his bodyguard may be mounted in a Wartrukk...". Does this mean I can only take the Trukk w/ the HQ if I also take a bodyguard with him?
I wanted to try a group of 8 Burna Boyz (4 burnas) with a Mek Boy (KFF) and then take a Big Mek with a Burna and a Trukk and have him join the Burna squad and put them all in the Trukk. But unsure if I can do this since the entry says, Big Mek and his bodyguard can take a Wartrukk.
As you said, it states that he must take the trukk with a bodyguard - an attached unit doesn't count as a bodyguard.
The only way you could do that, is in a Kult of Speed army, in which you could just put the Big Mek inside the Trukk.
Hope that helps.
Dernit! Ok thanks! Maybe I'll switch the Burna Squad to a Big Mek w/ Mekboy BG w/ Burnas squad...
