scout helicopter and having three RQ-7 Shadow platoons organically assigned; the attack battalions will also be aligned with an MQ-1C Gray Eagle company assigned to each division. Moving Shadows from brigade combat team level to the battalions themselves reduces lines of communication, distance issues, and allows operators and pilots to better train and work together. In early July 2014, the U.S. Army sent RQ-7 Shadows to Baghdad as part of efforts to protect embassy personnel against Islamic State militant attacks, along with Apache attack helicopters which could use them through manned and unmanned teaming to share information and designate targets. On 29 July 2018, the U.S. Marine conducted its final launch of the RQ-7B during RIMPAC exercises before retiring it. Since first deploying with Marines to Iraq in October 2007, the aircraft eventually equipped four tactical UAS squadrons, flying some 39,000 hours during 11 operational deployments. The Shadow was replaced by the RQ-21 Blackjack, which was first deployed in 2014. In March 2019, the U.S. Army selected Martin UAV and AAI Corporation to "provide unmanned aircraft systems for platoons to try out as candidates to replace the Shadow tactical UAS." The Army seeks better acoustics and runway independence as compared to the old Shadow, as well as lower equipment requirements. Shortly after the selection of the first teams, L3Harris Technologies and Arcturus-UAV (later under AeroVironment) were also picked to submit candidates. The four aircraft were used to evaluate requirements and assess new capabilities, and in August 2021 the Army decided to proceed with a competition for the Future Tactical Unmanned Aircraft System (FTUAS); a fielding decision is planned for 2025. The Army chose the AeroVironment Jump 20 in August 2022. The procurement will inform requirements for a second program increment, which will rely on a separate competitive acquisition. Although the Army plans to replace the Shadow in brigade combat teams, it will continue to be used by combat aviation brigades and special forces units into the mid-2030s. Variants RQ-7A Shadow The RQ-7A was the initial version of the Shadow 200 UAS developed by AAI. The first low-rate initial-production systems were delivered to the US Army in 2002 with the first full-scale production systems being delivered in September 2003. The RQ-7A was long and had a wingspan of with a max takeoff weight. The aircraft's endurance ranged between 4 and 5.5 hours depending on mission. The "A" model aircraft also had
