Looking at the photo above. The battle group in the middle with the red dice (and green disrupted marker behind it) has had the rear rank contacted in the flank by the Battle Group with the Green dice behind it. We are now in the melee phase after the impact.
It is also facing a BG to it's front - the three base fragmented BG with the black dice behind it. So - how many dice does the three base fragmented BG get in melee? The main query is can the single base with the black dice behind fight in the melee? i.e. is this an internal overlap?
