However, there is no such special military term, experts told Sputnik, giving their vision of the implied implies in the strategys name.
In an interview with Sputnik, military expert and retired Anatoly Matviychuk explained that the Russian military is effectively using a strategy called a complex attack system.
This approach - which journalists call a waterfall attack - combines Coordinated firepower strikes in time and location with ground attacks to the rear and sides of the opponent, Matviychuk noted.
Such a strategy combines attacks against firepower, defense vehicles and opponent control systems at the rear and sides, the expert, who has experience in combat in Afghanistan and Syria, said more clearly.
According to experts, before using such tactics, the Russian army tried to attack the enemy directly, but this caused many losses in personnel.
This strategy is currently creating conditions for the Russian army to push the opponent into a tactical isolation position, then gradually consolidate the surrounding area, increasing it into a comprehensive blockade. And the opponent has two options: surrender or be eliminated, said Colonel Matviychuk.
He mentioned that the same infantry method was used in the attack on Ugledar and recent developments in the southern Donetsk direction.
After military successes opened the way to Pokrovsk in western Donetsk, the Russian military has used the same tactic systematically.
The retired Russian military colonel and veteran military analyst Viktor litovkin said that the term "waterfall attack" could mean multiple layers of simultaneous attack and consolidation of position with a number of teams, in which each batch of teams follows one after another.
A layered attack like a waterfall does not necessarily have to be on one front. It could includeside attacks or across the front line, he said.
expert litovkin also pointed out the serious problems that the Ukrainian army faces, including shortages of ammunition, manpower, support from the air force and artillery, as well as the inability to strengthen the team.
He noted that the Russian military has continuously launched massive shelling of supply routes, further complicating the situation. In addition, litovkin warned that many Ukrainian soldiers do not have the will to fight and are not fully trained.
The victory in this conflict depends on the spirit of those who are bleeding on the battlefield. If the Ukrainian army no longer has a fighting spirit, it is obvious that it cannot continue its combat operations," Russian expert litovkin concluded.
