All craft over water can sink; just because it 'floats' on a bed of
air, does not make it invunerable to damage to its skirts
etc.
By the Way
Amphibious MBT are not designed to assault beacheads, just to ford
rivers with less than 5m depth. In all usual situations, you need
wide enuff approaches and strong ingress and egress with no
underwater obstacles. Seldom seen in SE Asia because of the soft
terrain (i.e. tidal swamps etc)
Singapore practices coastal hooks, not OTH assaults. Even with our
LST SS Endurance, without a proper or dedicated support/bombardment
vessels cannot 'hit the beaches' USMC style.
Book in Nat Library "Ambhibious Warfare" is good guide on such
matters.
