Originally T'zanhanim (, "Paratroopers") company's officers were the biggest opposition against the creation of Unit 101. The reason for this was simply that they didn't want another competitor for retaliation missions. Before the formation of Unit 101 only they undertook these missions. One of the unit's tactical commanders was Meir Har-Zion, who was later awarded the rank of an officer solely for his conduct in battle. The tactics of Unit 101 was politically very effective and soon the fighters simply could not keep up with the attrition.
