Why did Ariel Sharon resign from the Israeli army in 1973?

Ariel Sharon resigned from the Israeli army in July 1973 primarily due to his reputation for being impulsive, uncontrollable, and dogmatic, which created many enemies and prevented him from attaining the top military position he desired. Following his resignation, he retired to his ranch in the Negev desert.1

It is important to note that while he resigned in July 1973, he was recalled to active service at the start of the Yom Kippur War in October 1973. He later departed the armed forces permanently for a career in politics in January 1974, following a public denunciation of his fellow generals that the army officially labeled a violation of military discipline.2
