Foreword
It’s possible. But he has already left the map so you don’t get to change the story, and since you don’t get xp from kill you are wasting valuable bullets, explosives, and health.
How-To
It might take a few reload due to rng, but you can easily destroy that blockade. First, use your machine gunner to kill the two units on the unpathable high ground. Then make a line just outside of their farthest vision unit. Send your riflemen slightly ahead of everyone and have him bayonet charge one of their soldiers.
He should be able to tank most of the shots due to increase defense from the charge. Everyone else should follow immediate to the cover spots while the two grenadiers throw their grenades to overlap the vehicles and turrets. Two grenade will destroy both turrets and vehicles. Then kill the rest with your machine gunner or more grenades.
Pause to set your positions, give all the commands, then F5 to save. Reload if your rifleman dies too quick, or your grenadiers get hit before throwing their grenades.
However, it seems Morozov has already left in another vehicle, so there is no effect/reward for destroying those units. Just a silly trap to waste ammo and health.
My method: laying mines at the line of sight of heavy machine guns and armored vehicles. Subsequently, I lured them with the movement of the platoon. One hit a mine and was destroyed. The second one returned to its original position and I lured it out by killing the two soldiers who are behind the fence in the upper right corner. The second vehicle moved to their position and I subsequently destroyed it with grenades. I managed to charge the machine gun position with the help of micro management, bayonet charge and grenades. It is important to line up the soldiers behind the cover by the machine gun so that at least one medic survives and ideally both grenadiers. I was unable to do so without injury.
