aviation brigades with 60 armed reconnaissance helicopters and no Apaches, with the remaining structure the same. The remaining divisions will have aviation brigades with 30 armed reconnaissance helicopters and 24 Apaches, with the remaining structure the same. Ten Army Apache helicopter units will convert to heavy attack reconnaissance squadrons, with 12 RQ-7B Shadow drones apiece. The helicopters to fill out these large, combined-arms division-level aviation brigades comes from aviation units that used to reside at the corps-level. Field Artillery Brigades (formerly known as "Fires Brigades" prior to 2014) provide traditional artillery fire (Paladin Howitzer, M270 MLRS, HIMARS) as well as information operations and non-lethal effects capabilities. After the 2013 reform, the expertise formerly embodied in the pre-2007 Division Artillery (DIVARTY) was formally re-instituted in the Division Artillery Brigades of 2015. The operational Fires battalions will now report to this new formulation of DIVARTY, for training and operational Fires standards, as well as to the BCT. Air Defense: The Army will no longer provide an organic air defense artillery (ADA) battalion to its divisions. Nine of the ten active component (AC) divisional ADA battalions and two of the eight reserve (ARNG) divisional ADA battalions will deactivate. The remaining AC divisional ADA battalion along with six ARNG divisional ADA battalions will be pooled at the Unit of Employment to provide on-call air and missile defense (AMD) protection. The pool of Army AMD resources will address operational requirements in a tailorable and timely manner without stripping assigned AMD capability from other missions. Maneuver short-range air defense (MSHORAD) with laser cannon prototypes are fielding by 2020. Maneuver Enhancement Brigades are designed to be self-contained, and will command units such as chemical, military police, civil affairs units, and tactical units such as a maneuver infantry battalion. These formations are designed to be joint so that they can operate with coalition, or joint forces such as the Marine Corps, or can span the gap between modular combat brigades and other modular support brigades. Sustainment Brigades provide echelon-above-brigade-level logistics. On its rotation to South Korea, 3rd ABCT, 1st Armored Division deployed its supply support activity (SSA) common authorized stockage list (CASL) as well. The CASL allows the ABCT to draw additional stocks beyond its pipeline of materiel from GCSS-A. The DoD-level Global Combat Support System includes an Army-level tool (GCSS-A), which runs on tablet computers with bar code readers which 92-A specialists use to enter and track
