Introduction
How is the Military in Israel and how does it work to maintain Sucity and fight terrorism? In terms of Military and security forces, we have the Israel Defense Forces (IDF): Ground Forces, Israel Naval Force (IN, includes commandos), Israel Air Force (IAF, includes air defense) (2024).
In Israel, the IDF is responsible for external defense but also has some domestic security responsibilities; its primary operational focuses include the threat posed by Iran, instability in Syria, and terrorist organizations, including HAMAS, Hizballah, the Islamic State of Iraq and ash-Sham (ISIS), and Palestine Islamic Jihad (PIJ); it has considerable experience in conventional and unconventional warfare; since the country’s founding in 1948, the IDF has been in conflicts against one or more of its Arab neighbors in 1948-49, 1956, 1967, 1967-70 (“War of Attrition”), 1973, 1982, and 2006; it bombed nuclear sites in Iraq in 1981 and Syria in 2007, and since the outbreak of the Syrian civil war in 2011, has conducted numerous air strikes in Syria against Iranian, Iranian-backed militia, Hizballah, and Syrian Government targets; over the same period, the IDF has carried out strikes against Hizballah in Lebanon in response to attacks on Israeli territory; the IDF has conducted numerous operations against HAMAS and PIJ, which operate out of the Gaza Strip and have launched dozens of rocket attacks against Israel; HAMAS and Israel fought an 11-day conflict in 2021, which ended in an informal truce, although sporadic clashes continued; in October 2023, HAMAS conducted a surprise ground assault from Gaza into Israel, supported by rockets and armed drones, killing more than 1,000 Israelis and foreigners living in Israel; the attack resulted in an IDF ground invasion of Gaza where fighting continued into 2024

since its creation from armed Jewish militias during the First Arab-Israeli War in 1948-49, the IDF, particularly the Ground Force, has been guided by a requirement to rapidly mobilize and defend the country’s territory from numerically superior neighboring countries; the active-duty military is backed up by a large force of trained reserves--approximately 300-400,000 personnel--that can be mobilized rapidly 

Israel’s primary security partner is the US; consistent with a 10-year (2019-2028) Memorandum of Understanding, the US annually provides over $3 billion in military financing and cooperative military programs, such as missile defense; the US also provides Israel access to US-produced military weapons systems including advanced fighter aircraft; Israel has Major Non-NATO Ally status with the US, a designation under US law that provides foreign partners with certain benefits in the areas of defense trade and security cooperation

the United Nations Disengagement Observer Force (UNDOF) has operated in the Golan between Israel and Syria since 1974 to monitor the ceasefire following the 1973 Arab-Israeli War and supervise the areas of separation between the two countries; UNDOF consists of about 1,000 military personnel (2024)
