Troops from Russia, Belarus and Serbia have eliminated ‘terrorists’ and carried out airdrops during joint drills in Belarus. The forces trained together at a real strategic site for the very first time.

The active phase of the international 2017 Slavic Brotherhood tactical anti-terrorism exercises began outside the Belarusian city of Brest on Monday.

The first stage of the active phase included the deployment of a multinational battalion tactical group formed of Russian, Belarusian and Serbian troops.

“This morning the first stage of the active drills phase has begun – preparing the battalion tactical group formed of Russian, Belarusian and Serbian troops to perform anti-terrorist tasks and a march towards the designated area with crossing water bodies and airborne deployment,” Russian Colonel Aleksey Sbignev told reporters.

Some 10 tactical exercises, which also included airborne deployment, were carried out during the first day of the active phase, the commander added.

A number of tasks have been performed for the very first time during the yearly joint drills of the three countries, according to Deputy Commander of the Russian Airborne Troops Lieutenant General Nikolay Ignatov, who is attending the drills as an observer.

The international battalion tactical group, also formed for the very first time, has been training at a real strategic site – a hydro technical installation which was ‘captured’ and prepared to be destroyed by mock terrorists, according to details of the drills.

Among the practiced tactics at the war games is also securing territory from insurgents, as well as the evacuation of wounded personnel, according to Russia’s Defense Ministry.

The drills began on June 6, and until June 11 the troops honed cooperation within the international tactical battalion group created for counter-terrorism activities.
