Below is a note from the publisher, Scott Fisher of Skirmish Campaigns.
Also – wanted to write a quick note to tell you all that our latest scenario book, Tonkin Gulf Yacht Club, which covers the US Navy in Vietnam from 1965-68 was released at Fall-In, Nov’2019 (cover below). It really is a masterwork from Tom Ballou with lots of new details and great small stories. To write this book, Tom was part of veteran chat groups, has done many interviews, and has packed the book with more optional historically-based rules than all CY6 books to date combined (!) [only sort-of kidding here]
