Planning had begun in 1971 and was conducted in absolute secrecy—even the upper-echelon commanders were not told of the war plans until less than a week prior to the attack, and the soldiers were not told until a few hours beforehand.
Planeerimine oli alanud 1971 ja see toimus täielikus saladuses – isegi kõrged sõjaväelased said plaanist teada vähem kui nädal enne rünnakut ja sõduritele räägiti sellest mõni tund enne sõja algust.
