What's the name of the soldier who went to the enemy to destroy mines or something

An army engineer staff officer who had the honor to participate in the self-defense counterattack against Vietnam in February 1979 answered the questioner: In the past, destroying enemy mines on the battlefield could be done by any arms (for example, in the war that started in February 1979, ordinary officers and men rolled into the minefield to clear the way), but now there are armored forces to destroy mines and armored vehicles. It is the army engineers who want to eliminate the role of mines in a professional and safe way.
