Russia, the largest country in the world, has shown its mortar system, which is considered by experts as the world’s largest.

In a recent video that went viral, the Russian Armed Forces showed off their training exercises using unmanned aerial vehicles, tanks, and their largest mortar system.

The video was reportedly shot in a military range that is located outside the Orenburg city, which is located in the south-western Russian region of Orenburg Oblast, bordering with Kazakhstan.

The Central Military District, which is one of the 5 military districts of the Russian Armed Forces, took part in the exercise using unmanned aerial vehicles, tanks, howitzers, and truck-mounted rocket launchers.

According to the Russian Ministry of Defence, scouts used unmanned aerial vehicles to discover a hidden base in the remote region that was interconnected by tunnels.

In a statement that was released by the Russian Ministry of Defence, they said:

“Attacks on different positions of the enemy’s base took place simultaneously using 152-mm 2S19 Msta self-propelled howitzers and Grad and Uragan multiple rocket launchers.”

The underground tunnels and structures were attacked.

According to reports, the attacks were carried out with 2S4 Tyulpan, a Soviet 240 mm self-propelled heavy mortar.

The Russian Ministry of Defence said over 250 directs were reported against the enemy.

The 2S19 Msta-S is a 152.4 mm self-propelled howitzer, which entered service in 1989 as the successor to the 2S3 Akatsiya.

The BM-21 Grad is a Soviet truck-mounted 22 mm multiple rocket launcher.

The BM-27 Uragan is a self-propelled multiple rocket launcher system that was designed decades ago in Russia.

The Uragan was deployed in service in the late 1970s and was its first modern spin and fin stabilized heavy multiple rocket launcher.

The 2S4 Tyulpan is a Soviet 240 mm self-propelled heavy mortar and is the largest mortar system that is deployed in militaries today.
