Task Force ODIN
Task Force ODIN, whose name is an acronym for observe, detect, identify, and neutralize, is a United States Army aviation battalion created in August 2006 to conduct reconnaissance, surveillance and target acquisition (RSTA) operations to combat insurgent operators of improvised explosive devices in Iraq.
The unit was formed at Fort Hood, Texas, and first deployed in October 2006. An Army article says the unit is meant to meet "the critical requirement to 'win back the roads' using Army Aviation assets to maintain a persistent stare over demonstrated at-risk areas for IEDs." The United States Army stood up TF ODIN as a Quick Reaction Capabilities project whose efficacy proved so effective it shaped the Secretary of Defense Directive to establish the Air Force Project Liberty and other ISR related missions. 
ODIN is the Army's only unit that flies the MQ-1B Warrior-Alpha unmanned aerial vehicle. Built by General Atomics Aeronautical Systems, the extended-range multi-purpose hybrid UAV has an advanced sensor package incorporating electro-optical sensors, including FLIR, and synthetic aperture radar together with a laser rangefinder and a laser designator, the latter for "painting" targets for strikes with Hellfire missiles and laser-guided bombs.
The Army established a sister, TF ODIN-A, unit in Afghanistan. After "Operation New Dawn" (OND), TF ODIN was temporarily positioned in an undisclosed location until further movement into Afghanistan to combine both TF-ODIN and TF-ODIN-A as TF-ODIN-E Operation Enduring Freedom. There are many sub-divisions in the task force: Highlighter, Desert Owl and Night Eagle to name a few.
According to General David Petraeus in August 2010, during the previous 90 days in Afghanistan information provided by ODIN had resulted in the killing or capture of 365 militant leaders, detained 1,335 insurgent foot soldiers, and killed another 1,031 Taliban.
