Per the US Army in their Waypoint 2028 (Now Army 2030) briefings they will be Armor Battalions. One in each Joint Forcible Entry Division - Airborne and Joint Forcible Entry Division - Air Assault. As well each Standard Division, Light (how ever many of those there will be) will get a single Armor Battalion.Vehicles will be on the TO&E of both the 82nd and 101st Airborne, as well as other light infantry units. How the vehicle will be utilised, its tactics, Light Infantry unit numbers etc., haven't yet been determined and that is being formulated as part of the introduction into service. The Army has approved a LRIP of unknown quantity.
I assume the 82nd's battalion will be 4/68th AR. They used A/4/68th as their MPF surrogate unit while using the LAV-25 a couple years ago (2018-2020). 4/68th AR was the original designation of the Sheridan battalion before it was redesignated 3/73rd AR in the mid-80's. But 73rd AR was redesignated as a Cav Rgt and 1, 3 & 5 Sqns 73rd CAV currently serve as the 82nds RSTA squadrons. (1/17 CAV is their Attack Reconnaissance Squadron in the Cbt Avn Bde) . The JFED-Abn/AAslt are briefed as retaining a divisional ground CAV Sqn plus a ground CAV Trp in each BCT, which I assume will retain the 73rd CAV unit designations in the 82nd
(Reminder: Sqn = Bn size, Trp = Co size for you "Commonwealth" nomenclature folks )
