Ukraine's 46th Airmobile Brigade repulsing two Russian attacks. The enemy tank can be seen having to slow down in front of the concrete ‘dragon's teeth’ in order to use its gun fire to make a passage through them, while FPV drones are working on it. As has been repeated many times before, the engineering barriers themselves are pretty pointless, as the enemy will always be able to overcome them in a certain amount of time. At the same time, if the defenders are actively firing, the engineer barriers can significantly help - to delay the attacker or to direct him to a convenient and planned place for a fire bag.
