Amphibious warfare became faster and heavier

How much has amphibious warfare changed across history?

Less than expected: it is faster and heavier, while the enduring challenge remains moving and sustaining combat power from ships to shore.

Amphibious warfare has changed less across history than its equipment suggests. Modern landings are faster and carry heavier combat power, and a tank can be driven onto a landing craft more predictably than a horse can be transferred between boats. Tanks also weigh far more and consume fuel on a scale that makes sustainment difficult. The enduring problem is moving people, animals, or machines through constrained ship-to-shore routes and then keeping them supplied ashore.
