Возник вопрос - все таки какой кавер сейв имеет орочья техника в чистом поле, под действием КФФ? Есть мысль, что 5+, и вот почему.
Вординг КФФ:
A kustom force field gives all units within 6" of a Mek a cover save of 5+. Vehicles within 6" are treated as being obscured targets
Далее, РБ, стр. 62:
If the target is obscured and suffers a glancing or penetrating hit, it may take a cover save against it, exactly like a non-vehicle model would do against a wound (for example, a save of 5+ for a hedge, 4+ for a building, 3+ for a fortification, and so on). If the save is passed, the hit is discarded and no roll is made on the Vehicle Damage table.
If a special rule or a piece of wargear confers to a vehicle the ability of being obscured even if in the open, this is a 4+ cover save, unless specified otherwise in the Codex.
Т.е., получается, что КФФ дает всем кавер сейв 5+, и, в соответствии с рульбуком, технике тоже.
