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=55748.0Has the ruling, which stated completely submerged was required for a critical hit, changed? (It was a couple of years ago.)
