&gt; The Russians don&#x27;t rely as much combat air support -<p>Russia is not using aircraft in Ukraine because regular Russian military is not &quot;technically&quot; there. It&#x27;s kinda hard to deny your presence if your planes are bombing the country. Most of Ukraine&#x27;s meager air fleet was grounded in the beginning of conflict so that whole thing turned into artillery war.<p>On another hand take a look at Syria. Pretty much everything Russia does there is air support.
