Hi, Im new to the site but have been doing family tree research for few years. I'm trying to understand bit about my granddads war. I have his service record and release book. I have a couple of stories from his time in Sicily and Italy. But I really want to be able know his full story i.e was he involved in combat. I am very confused by different units, companys(coys), brigades. I can't find anything on web relating to those. If anybody can help id be so grateful.
