In the IDF, Gur served in the Paratroopers Brigade most of his career and became one of the symbols of the "red beret" brigade. During the 1950s he was a company commander under the command of Ariel Sharon. He was wounded during a counter-terror raid in Khan Yunis in 1955 (Operation Elkayam) and received a recommendation of honor from Chief of Staff Moshe Dayan. In 1957 he was appointed as adjutant to the brigade commander. After serving in this position Gur went to study at the École Supérieure de Guerre in Paris.
