Israel Rebuilds Military Open-Source Intelligence Unit After Oct 7 Failures
Aman has revived and expanded its historical open-source intelligence unit, 'Hatzav', following critical intelligence failures identified in the October 7 attacks.
Israel's military intelligence directorate, Aman, has officially revived and expanded its open-source intelligence (OSINT) unit, known historically as 'Hatzav', following critical lessons learned from the October 7, 2023 massacres. The original unit, which had operated for 72 years monitoring Arabic-language media and public broadcasts, was systematically downsized and ultimately disbanded in 2021 under former Aman chiefs Tamir Hayman and Aharon Haliva. Military leadership at the time favored high-tech cyber intelligence and signals intelligence (SIGINT), relegating OSINT to a peripheral, underfunded status.
The Failure of the Conception
In the years leading up to Hamas's assault, the terror group openly published extensive training footage, propaganda videos detailing border breaches, and inflammatory speeches by leadership, including Yahya Sinwar. Despite this vast public trail, analysts argue that a deep-seated conception within Aman—the belief that Hamas was deterred and uninterested in a large-scale war—prevented intelligence officers from taking these open-source warnings seriously. The disbandment of Hatzav dispersed open-source duties among regular researchers who lacked specialized linguistic and cultural nuance training.
The conception was so deeply rooted within the intelligence directorate that no video of Nukhba training or Ramadan invasion drama could have changed it, says a former senior defense official.
Rebirth and Modernization under Binder
Following the failures of October 7, current Aman chief Major General Shlomi Binder spearheaded the creation of a new, vastly expanded OSINT apparatus. Unlike its modest predecessor, the new directorate answers directly to the head of Aman, holding equal structural weight to Unit 8200 and the Research Division. Staffed by tripled personnel and equipped with advanced artificial intelligence tools, the reborn unit focuses on cross-referencing public data, social media trends, and regional broadcasts to provide tactical and strategic insights.
Tactical and Strategic Impact
The modernized OSINT unit has already proven its operational value, contributing significantly to recent military campaigns by analyzing social media geolocations, monitoring hostile regional networks, and assisting in hostage-recovery efforts. While military officials emphasize that artificial intelligence must be carefully balanced with human analysis and deep regional expertise, the resurrection of Israel's open-source capabilities marks a permanent cultural shift in how military intelligence assesses threats.
