I was reading an unrelated thread on dakka when somebody mentioned that a person could take a elite from say a space marine army, and simply use it say in an imperial guard as an elites choice. This is the exact quote and my question is , is this the way it works? This was in the context of gray knights having no snipers and taking the assassin. "You can literally just take an elite slot in a detachment and stuff a Vindicare in it. HQ: Draigo and Voldus, Troops: 3x Terminators, Elite: Vindicator. Done. There's a Battalion."
