From the announcement:
Speaking of free miniatures we plan to follow this theme with the rest of the Bolt Action supplements. For example, we’ll have the US Marine Corp’s ‘Chesty’ Puller for the Armies of America supplement. You’ll only be able to get your hands on these superb character models by purchasing these titles from us here at Warlord Games. As we get nearer to publishing dates we’ll bring you all the news and pre-order info – stay tuned!
