>Airstrikes would not go entirely uncontested. Russia’s air force lacks experience in suppressing or destroying enemy air defenses, and it rarely uses missiles that are designed to destroy radar. As a result, Ukraine’s meager air defenses could still pose a challenge. But Ukrainian air defenses are in short supply, and they would be unlikely to provide effective cover for most of the country’s ground troops. They would be quickly overwhelmed.
>The opening air campaign would probably be short. Unlike Western militaries, which concentrate firepower in their air forces, Russia puts the bulk of its firepower in its ground forces, so it would quickly proceed to a ground campaign.
