A year and a half later, on the direct orders of the Prime Minister, Sharon returned to active service in the rank of major, as the founder and commander of the new Unit 101, a special forces unit tasked with reprisal operations in response to Palestinian fedayeen attacks.
The first Israeli commando unit, Unit 101 specialized in offensive guerrilla warfare in enemy countries.
The unit consisted of 50 men, mostly former paratroopers and Unit 30 personnel.
They were armed with non-standard weapons and tasked with carrying out special reprisals across the state's borders— mainly establishing small unit maneuvers, activation and insertion tactics.
Training included engaging enemy forces across Israel's borders.
Israeli historian Benny Morris describes Unit 101:
The new recruits began a harsh regimen of day and night training, their orientation and navigation exercises often taking them across the border; encounters with enemy patrols or village watchmen were regarded as the best preparation for the missions that lay ahead.
Some commanders, such as Baum and Sharon, deliberately sought firefights.

— Benny Morris, Israel's Border Wars
Unit 101 undertook a series of raids against Jordan, which then held the West Bank.
The raids also helped bolster Israeli morale and convince Arab states that the fledgling nation was capable of long-range military action.
Known for raids against Arab civilians and military targets, the unit is held responsible for the widely condemned Qibya massacre in the fall of 1953.
After a group of Palestinians used Qibya as a staging point for a fedayeen attack in Yehud that killed a Jewish woman and her two children in Israel, Unit 101 retaliated on the village.
By various accounts of the ensuing attack, 65 to 70 Palestinian civilians, half of them women and children, were killed when Sharon's troops dynamited 45 houses and a school.

Facing international condemnation for the attack, Ben-Gurion denied that the Israeli military was involved.
In his memoir, Sharon wrote that the unit had checked all the houses before detonating the explosives and that he thought the houses were empty.
Although he admitted the results were tragic, Sharon defended the attack, however: "Now people could feel that the terrorist gangs would think twice before striking, now that they knew for sure they would be hit back.
Kibbya also put the Jordanian and Egyptian governments on notice that if Israel was vulnerable, so were they."

A few months after its founding, Unit 101 was merged with the 890 Paratroopers Battalion to create the Paratroopers Brigade, of which Sharon would also later become commander.
Like Unit 101, it continued raids into Arab territory, culminating with the attack on the Qalqilyah police station in the autumn of 1956.

Leading up to the Suez War, the missions Sharon took part in included:
Operation Shoshana (now known as the Qibya massacre)
Operation Black Arrow
Operation Elkayam
Operation Egged
Operation Olive Leaves
Operation Volcano
Operation Gulliver (מבצע גוליבר)
Operation Lulav (מבצע לולב)
During a payback operation in the Deir al-Balah refugee camp in the Gaza Strip, Sharon was again wounded by gunfire, this time in the leg.
Incidents such as those involving Meir Har-Zion, along with many others, contributed to the tension between Prime Minister Moshe Sharett, who often opposed Sharon's raids, and Moshe Dayan, who had become increasingly ambivalent in his feelings towards Sharon.
Later in the year, Sharon was investigated and tried by the Military Police for disciplining one of his subordinates.
However, the charges were dismissed before the onset of the Suez War.
