10.3 seems crystal clear: "Any silhouette (artwork) of blocking terrain crossed by a LOS blocks it (except as otherwise noted). Degrading-terrain silhouettes don’t block LOS, they degrade it." In Heroes of the Nam, the artwork for huts includes a depiction of a small tree or some other kind of vegetation next to the hut. In the attached screenshot, LOS is being traced through hex K4 where it touches a branch of one of those trees, but not the hut itself. A literal reading of the rules seems to suggest LOS is blocked. Is it really the case that this single tree branch blocks LOS, whereas an entire hex full of light jungle, for example, only degrades it?
