Hello, my questios about this batallion trigger on being attacked with unmodified wound roll of 6 is, does it trigger each 6 o you just need a 6 on the wound rolls and after all attacks are done, attacker receives 1 Mortal Wound even if he rolls multiple 6's on wounds?

It looks like it is only one MW back regardless of number of sixes to wound rolled. It`s similary worded to command ability of Deamon Prince of Nurgle. If it was for all sixes it would say something like "for each six" like on Khinerai heartpiercer shields for example.
