Mature amphibious doctrine could transform Gallipoli

What if Britain entered the First World War with mature amphibious doctrine and the necessary equipment?

Gallipoli could succeed, opening supply to Russia and potentially delaying or redirecting the Russian Revolution even if it did not prevent upheaval entirely.

The historical campaign suffered from divided command, inadequate landing arrangements, poor intelligence, and weak coordination between ships and troops. Giving Britain mature doctrine and suitable equipment makes a rapid, mutually supporting assault much more plausible. Success could open the route through the Dardanelles and restore supply to Russia. Russia might still experience revolution, but a longer war effort could change its timing and whether a republican or Bolshevik government prevails.
