With air superiority, your army may operate as it sees fit, having freedom of the battlefield.  Without it, you will likely lose battle after battle as your troops are not only bombarded from above, but their movements are anticipated and countered.<p>Example of the latter: The Ottoman Empire&#x27;s attempt to take the Suez Canal in 1915 via overland march. The movements of their approaching army were reported to the British &amp; Indian troops by the new &quot;wonder weapon&quot; of the age - the aeroplane.  The Turks lost 2000 men, the British 150.<p><i>Edit:</i>
