Since Israel is a country of immigrants, the fighting methods came from many countries.
The first methods were probably and mostly Soviet and German.
Later on, the methods came from different armies: the special forces for example, from the British special forces (some methods were adopted during the British mandate by the Haganah, while others after the establishment of the IDF).
As the years and wars passed on, Israel became a leader of fighting methods.
For example, the IDF elite unit Sayeret Matkal was based on the British SAS, but later it adopted Israeli methods, based on the experience of Israel from the Israeli-Arab wars and conflicts.
Its worth to note that today armies around the world (such as the American and Indian armies) are adopting Israeli developed methods, such as the Krav Maga, air combat skills, Israeli special forces methods, etc.
It's tempting to say that Israeli doctrine is derived from the original draft of Maneuver War, ie. Germany (circa 1915). The Imperial German Army had many Jewish officers (most were 'reservists' due to the anti-semitic attitudes that existed under the Kaiser). German-Jews (WWI vets) emigrating to Palestine during the inter-War years could have brought military training manuals along with them and used these as the basis for training some of the Israeli militias in the '20's & '30's. Only problem with this theory is that nobody can name a significant Israeli military figure from that period who "fits that description", nor can you really point to any doctrinal writings that fit the German 'template'.
That leaves the Soviet-model of the '30's. Before Stalin's purge of the Soviet Military, the Soviets were leaders in Maneuver Doctrine. Therefore, I 'lean' toward the Soviet template. But I gotta tell ya, some of the armor and CAS tactics sure 'look' like the German Blitzkrieg.
Remember there was Kirk Douglas movie talking about that long time ago
Sometime TCM show that movie one thing for sure John Wayne play General who gave authroize of Kirk Douglas go into Israel and help training then Israeli miltia
Great series. Thank you.
The IDF was modelled on the Swiss Army - a small country whose entire male population within an age range could be mobilized. In Switzerland, all adult males are legally required to own a firearm which is government issued upon majority age.
"In the postwar years, until 1956, the Arab states maintained the military pressure by supporting terrorist and guerrilla infiltration across the borders. The continual pressure on the Army, together with the country's very limited financial resources and population, led to the creation of a small standing army backed by a very large reserve force. The principle was Swiss, with major modifications."
