Rav Aluf is usually translated as "Lieutenant General", but is often considered to equate to a Field Marshal or five-star General[citation needed], since it is the most senior rank in the IDF. The rank is given only to the Chief of General Staff (Ramatkal), so there can only be one active Rav Aluf under regular circumstances. However this could change in a time of war. During the Yom Kippur War in 1973, retired Rav Aluf Haim Bar-Lev was called back into service, replacing Shmuel Gonen as the commander of the southern theater. Thus, along with chief of the general staff David Elazar (who succeeded Bar-Lev in that position the previous year), there were two people in active service holding the rank of Rav Aluf simultaneously.
