A narrower counterfactual would send late-war amphibious transport capacity back to the Norwegian campaign. That would free cruisers from carrying the landing force and let them concentrate on naval action. The distinction drawn is between landing craft already available and the ships needed to transport them. Clarke also recalls meeting minutes in which a planned light tank doubled in weight despite the navy allowing a fifty-percent margin. The example shows how changes to an army load could exceed the assumptions behind its naval transport.

Norway's landing-force transport problem and tank weight growth
Landing craft and the vessels carrying them were separate constraints, complicated by changes in tank weight.
