TO AU&E p115 FULLY AMPHIBIOUS (WHEELED AND TRACKED VEHICLES)
While on water, the amphibious vehicle is treated as a displacement hull naval vessel
for purposes of line of sight, hull breaching and sinking rules.
TW p198:
Hull Integrity
Naval Combat Vehicles that take damage may require a Hull
Integrity roll, as described in the Underwater section of Damage
(see Combat, p. 98). Submarines follow all the standard rules for
hull integrity.
Surface Vessels: Surface vessels follow all the rules for hull
integrity, except that only damage to such a vehicle’s front, side or
rear armor locations requires a Hull Integrity roll.
TW p121 Damage, Underwater Units
If all of a location’s armor is destroyed (whether this
occurred before the unit entered the water hex or while it is
submerged), that location is automatically breached.
