 Russia prepares thousands of tanks and hundreds of fighter jets for offensive. Russian occupiers have prepared 1,800 tanks, 3,950 armoured vehicles, 2,700 artillery systems, 810 multiple rocket launch systems, 400 fighter jets and 300 helicopters ready for a new offensive operation in Ukraine. Foreign policy writes about it, citing a Ukrainian military official speaking on condition of anonymity. Russia has also begun arming up and digging in for a coming offensive. The Ukrainian military estimates that Russia already has 1,800 tanks, 3,950 armoured vehicles, 2,700 artillery systems, 810 Soviet-era multiple rocket launch systems such as grad and smurch, 400 fighter jets and 300 helicopters ready for a new wave of attack. Russian officials estimate that Russian forces inside the country have surpassed the 300,000 mark. Estimates of Russian presence in Ukraine are significantly higher than the invading force that Russian President Vladimir Putin used to invade the country last February, and this time they are highly concentrated in eastern Ukraine. The Pentagon has described the Russian troops that have already been rushed to the battlefield to plug up defensive holes as ill-equipped, ill-trained and rushed, according to a senior US military official. The Pentagon believes that the Kremlin has begun sending in tens of thousands of troops to replace losses suffered from ongoing battles in the cities of Bakhmut and Solidar, but Kiev believes that Putin could go even further, drafting more new troops around the 24th of February anniversary of the full-scale invasion. It's much bigger than what took place in the first wave, the Ukrainian military official said. They are not paying attention to any casualties or losses. In the next 10 days, we expect a new, huge invasion, he said. Ukrainian Defense Minister Oleg S. Reznikov said that he expected a surge in Russian operations around the upcoming anniversary of the invasion on the 24th of February. Analysts and Ukrainian officials expect the brewing offensive to focus on eastern Ukraine. US and Western officials now estimate that about 200,000 Russian troops have been killed or wounded in battle.
