IDF Reimagines Defense Doctrine Three Years After October 7

Three years after the October 7th attacks, the Israel Defense Forces (IDF) is undergoing a fundamental transformation in its defense, alert, and readiness doctrines. The military has attacked approximately 100,000 targets across all fronts, with about 65,000 in Gaza and 28,000 in Lebanon and Syria. Israel faced over 31,000 projectiles fired from Gaza, Lebanon, Iran, Syria, and Yemen. During the war, 970 soldiers have fallen in operational circumstances, while over 70% of wounded soldiers have returned to service. In the West Bank, over 3,800 weapons were seized and some 45,000 suspects were apprehended.

A key lesson learned is the shift from waiting for the enemy to proactively eliminating threats. This is reflected in enhanced border defenses, fortified communities, and increased readiness. In the Northern Command, defense forces in communities have tripled, equipped with drones and advanced observation and communication tools. The Southern Command has upgraded fences, security roads, and observation posts, implementing the 'Nitz' app for encrypted communication and establishing new outposts. A massive physical and technological barrier has been erected along the Gaza border following the breach on October 7th.

The new defense concept is defined as 'army before civilians,' prioritizing the prevention of enemy entrenchment in areas affecting the home front and taking initiative to remove threats before they reach communities. This proactive approach is also being implemented in the Central Command, with communities being fortified and all camps designated as outposts. New territorial rapid response brigades have been established to counter emerging threats.

Intelligence Directorate (Aman) is also undergoing significant changes, prioritizing early warning of war or hostile activity as its central responsibility. New alert models have been developed, and a multi-domain, multi-disciplinary alert center has been established to create a unified intelligence picture. Aman is also fostering a culture of self-doubt, critical assessment of assessments, and identifying 'signals from reality' that contradict expectations.

The Air Force has quadrupled its readiness forces, and in some sectors, increased them sixfold. Cooperation with ground forces has deepened, with new units and pre-prepared target banks to shorten response times. The Navy has reorganized its security and defense zones, reinforced forces near combat areas, and established a new unit for forward combat collection. The logistics corps has also adapted to combat conditions, with a new school for combat administrative support and a program to accelerate forces' return to readiness.
