how is it that a dash is legal if the squads final hex is open ground? I'm probably just missing something simple here.
It is legal because this rule uses a pretty relative definition of Open Ground. It is only Open Ground if a DEFENDER can possible fire with the -1 FFMO DRM. So if all enemy units are out of LOS, or affected by some Hindrance, then this hex is not considered Open Ground. Check A10.531 for this definition of Open Ground.
Moreover, if one enemy unit has unhindered LOS to the hexes in question, the Dash is still legal, but does not receive Dash benefits when fired on by that specific enemy unit. It still receive Dash benefits when fired on by other enemy units though. So if there had been a British unit in U6, the 467 will not receive Dash benefits vs the U6 unit, but will still receive it vs the 458 in T7.
