maps, rather than paper maps, they can project scenarios which will also be used at PC22 in October and November 2022. In October 2022, the experiments from the previous Project Convergence were scaled up, from just Army in PC21 to joint and international exercises in PC22. AI was utilized not just for autonomous flight, but also for predicting where logistics would be needed in contested environments. PC22 experimented with some 300 technologies. Scenarios during PC22 included Tomahawk, SM-6, and LRHW missiles. 82nd Airborne participated in the PC22 experiments, using newly developed equipment. In November 2022, a contested logistics exercise, using an uninhabited Black Hawk helicopter under autonomous control was demonstrated at PC22. PC24 Project Convergence co-locates from WSMR and YPG (the hub), to allies and partners. PC24 could occur by spring 2024. Training and readiness Under Schoomaker, combat training centers (CTCs) emphasized the contemporary operating environment (such as an urban, ethnically-sensitive city in Iraq) and stress units according to the unit mission and the commanders' assessments, collaborating often to support holistic collective training programs, rather than by exception as was formerly the case. Schoomaker's plan was to resource units based on the mission they are expected to accomplish (major combat versus SASO, or stability and support operations), regardless of component (active or reserve). Instead of using snapshot readiness reports, the Army now rates units based on the mission they are expected to perform given their position across the three force pools ('reset', 'train/ready', and 'available'). The Army now deploys units upon each commanders' signature on the certificate of their unit's assessment (viz., Ready). As of June 2016, only one-third of the Army's brigades were ready to deploy. By 2019, two-thirds of the Active Army's brigades and half of the BCTs of the Total Army (both Active and Reserve components) are now at the highest level of readiness. The FY2021 budget request allows two-thirds of the Total Army (1,012,200 Soldiers by 2022) to reach the highest level of readiness by FY2022 —Maj. Gen. Paul Chamberlain. "Soldiers need to be ready 100 percent of the time."—Robert B. Abrams, FORSCOM commander, June 2, 2016 39th Chief of Staff Mark Milley's readiness objective is that all operational units be at 90 percent of the authorized strength in 2018, at 100 percent by 2021, and at 105 percent by 2023. The observer coach/trainers at the combat training centers, recruiters, and drill sergeants are to be
