(Answered) Partially submerged units & critical hits

[SC_Dave]

Hi,
I was hoping for an official ruling on this matter which came up in a thread outside rules questions:

"Quote from: nckestrel on 15 July 2019, 14:57:46
p41 Submerged Units.  water over your height = completely submerged.  water at least 1" deep but less than unit's height (ie. a mech) = partially submerged.  but both are submerged.
p48 Underwater Damage. Every successful attack against a submerged unit generated a Critical Hit, even if there is no structure damage."


This is at odds with what was posted in the official rules questions thread: https://bg.battletech.com/forums/index.php?topic=55748.0

Has the ruling, which stated completely submerged was required for a critical hit, changed? (It was a couple of years ago.)

Basically yes.
There was no "partially submerged" back then.  You were either completely submerged or not. And not submerged meant no critical hit.
Partially submerged has since been defined, counts as submerged, and therefore triggers critical hits from being submerged.
