A quick question I couldn't find any posts about.
Recently in a game a friend declared an assault against one of my units. The unit he was assaulting was so close to another of my units they were mixed together. When he started moving into base contact we found he couldn't get into base contact with only the one unit, they were so close that in order for him to get into base contact he HAD to contact the other unit. Now because he had to contact the other unit would he have to declare assaults against both units, thus getting overwatched by both units, or could he just declare against the one unit, getting overwatched by just the one unit, but also having to do a disorganized assault and not getting his extra attacks?
