These Videos Show Russian Troop Buildup Along The Ukraine Border (Watch)

With the U.S. warning that a Russian invasion of Ukraine can "happen anytime now," all eyes are now on the Russia-Ukraine border, where the troop buildup is reportedly accelerating.

Though Russia or its president Vladimir Putin denies any intention to invade Ukraine, social media is abuzz with videos and images that depict the brisk troop movements along the most volatile border in the world.

Of the many footages doing rounds, CNN has "geolocated and authenticated" a few of them. According to the reports, some of the videos are from official sources and often "often complement satellite imagery."

One video shows the movement of army tanks through the village of Sereteno, about 15 miles (24 kilometers) from the border. Other footages show tanks being offloaded from the trains and moving through snow-covered roads.

Scenes from Voronezh, a city in southwestern Russia, also show a large collection of tanks and infantry fighting vehicles, part of the Russian 1st Guards Tank Army, crowding the roads.

Choppers were also spotted near Belgorod, 40 kilometers north of the border with Ukraine. CNN report adds that the helicopters could have been brought as protection for ground troops in the event of an offensive. Tanks and infantry fighting vehicles, known as BMPs and self-propelled artillery, were also seen moving through the city.

Convoys of Iskander-M short-range ballistic missiles are also seen lined along the roads. Ukrainian Ministry of Defense recently said over 36 Iskander launchers have been lined close to the border, putting these missiles within the range of Kyiv.

These missiles will likely be used to attack fixed Ukrainian positions -- such as command and control sites. Each missile can carry a payload of up to 1,500 pounds that normally comprises a high-explosive or submunition warhead and can be instrumental if Moscow launches an offensive, said reports.

A barrage of missiles from Iskander-M systems would wreak havoc on all important Ukrainian defense infrastructure, that too without putting Russian airpower at risk.

"Russia's current military buildup near Ukraine is unprecedented," tweeted Rob Lee, from the Department of War Studies at King's College London. "This is not like previous war scares or the buildup in the spring [of 2021]. The amount of Russian aerial, ground, and naval military power near Ukraine now is quantifiably far greater."

Meanwhile, there are reports from Russia that its troops will return to their garrisons upon the completion of drills. Units of Russia’s Southern and Western Military Districts have begun loading their equipment for their departure, the report added.
