The T-64 tank is the most common variant used by the Ukrainian Army, with an estimated 1,000 in its inventory. While it may not be able to match the capabilities of Russian T-72 tanks, it can still put up a decent fight due to its 125mm smooth-bore gun and ability to use armor-piercing fin-stabilized discarding sabot (APFSDS) ammunition.

However, Russia’s T-72B3 and T-72B3M tanks are protected by advanced armor and ER (explosive reactive) armor, making them more formidable opponents. Ukraine also operates more modern variants of the T-64, including the T-64BM, which has improved armor and anti-tank missile capabilities. Additionally, they have hundreds of other tanks, including the T-72BS, T-80UD, and BVS, which are more up-to-date and capable of countering modern Russian armor.

Ukraine’s Air Force is relatively small and composed mainly of Soviet-era aircraft, which, unlike Russia, lacks modern aircraft. While they have S-300 air defense systems, they are less mobile and more vulnerable to Russian countermeasures. Ukraine’s Army has received significant numbers of anti-tank weapons, including the RPG-29 and the Javelin, which can penetrate heavily armored Russian tanks.

Despite having a capable military, Ukraine’s lack of a solid Air Force and artillery support will make it difficult for them to hold off Russian forces. The country’s Air Force is also unlikely to be a significant threat to Russia’s Air Force or its ground forces. In the event of an invasion, the capital, Kiev, may be taken within a few weeks, and some dedicated Ukrainians might attempt to form an insurgency, but it’s unlikely to succeed in overthrowing a pro-Russian government. Ultimately, the majority of Ukrainians may just want to restore peace and life under a more pro-Russian or pro-Western government, regardless of the outcome.
