He was born as Vladislovas Sabaliauskas in Tytuvėnai on March 31, 1910.^[1] Around 1911–1912, his father emigrated to the United States, while his mother joined him about one year later, and they returned to Lithuania in 1913. In 1921, she and her two sons, an 11-year-old Vladislovas and a 6-year-old Stanislovas emigrated to the United States and settled in Chicago.^[1] As a youth, Vladislovas began boxing and one of his idols was fellow Lithuanian Jack Sharkey. From 1929 to 1937, he was a professional boxer and won 31 of 33 bouts. His boxing career ended due to injuries sustained in a road accident.^[1]

Sabalauski entered the Army in June 1941. During World War II, he served in the Pacific theater, fighting on the beachheads of the Solomon Islands, Guadalcanal, and the Philippines. He later served in the Korean War with the 187th Regimental Combat Team (Airborne) and 25th Infantry Regiment. In 1963, Sabalauski went to Vietnam for the first time, where he served as an advisor to the 32nd Vietnamese Ranger Battalion. After service in the Dominican Republic in 1965, he returned to Vietnam in 1966. It was during this tour that he fought his most memorable battle.

Early in June 1966, Charlie Company, 2nd Battalion, 502nd Infantry Regiment, was conducting a mission to locate elements of the 24th North Vietnamese Regiment. Charlie Company made contact with what was estimated to be a battalion-sized enemy force. Under heavy enemy fire and unable to maneuver, company commander Captain William Carpenter called for air strikes in his position in an attempt to force the enemy to withdraw. The enemy ceased fire long enough to allow Charlie Company to consolidate, reorganize and establish a position from which to defend and begin evacuation of wounded personnel. First Sergeant Sabalauski repeatedly placed himself at risk for the sake of his soldiers during this mission. For his extraordinary heroism in destroying the enemy and in evacuating the casualties, he received both the Distinguished Service Cross and the Silver Star.

After his second tour in Vietnam, he returned to the United States to serve as Command Sergeant Major of the United States Corps of Cadets at West Point. In 1968, he again returned to Vietnam and the 2nd Battalion 502nd Infantry Regiment. His final assignment was as Command Sergeant Major of the 2nd Battalion, 508th Infantry Regiment of the 82nd Airborne Division at Fort Bragg from November 1970 until his retirement from the Army on April 1, 1972.

Command Sergeant Major Sabalauski's awards include the Distinguished Service Cross, Silver Star, Legion of Merit, 8 Bronze Stars, 3 Air Medals, 6 Army Commendation Medals, 4 Purple Hearts, 3 Awards of the Combat Infantryman Badge, the Master Parachutist Badge along with campaign medals for service in World War II, Korea, Dominican Republic, and Vietnam.

Command Sergeant Major Sabalauski died in 1993 and was buried with full military honors in Arlington National Cemetery.

The Sabalauski Air Assault School located in Fort Campbell, Kentucky was renamed in his honor in 1994.
