Bar Lev suggested that such a line would defend against any major Egyptian assault across the canal, and was expected to function as a "graveyard for Egyptian troops". Moshe Dayan described it as "one of the best anti-tank ditches in the world." Sharon, and Israel Tal on the other hand, vigorously opposed the line. Sharon said that it would pin down large military formations that would be sitting ducks for deadly artillery attacks, and cited the opinion of Rabbi Menachem M. Schneerson, who explained him "the great military disaster such a line could bring." Notwithstanding, it was completed in spring 1970.
