High Quality Content by WIKIPEDIA articles! Saganami Island Tactical Simulator (SITS) is a tabletop wargame set in the Honorverse, a series of military science fiction novels written by David Weber and others and published by Baen Books. The first edition was based on the Attack Vector: Tactical game engine, whereas the second edition featured a rewrite of those rules. Originally published in 2005 by Ad Astra Games, the second edition was published in 2007, and is based on the as yet unreleased Squadron Strike movement engine, which uses whole turn pre-plotted movement, rather than segmented movement and time keeping.
