Well a few of the reasons the stingray would not be used
1.its not a main battle tank
2.it was constructed in Slidell, Louisiana, U.S. (which is under Mexican rule in red dawn)

3.its has no advantages over the current U.S. tanks other then cost (yes it was even slower then the M1 tank)
4. cost to kill ratio was to low only had 23mm armor at is best.
cost 1.5 million per unit (4.3 million for M1) kill rate stranded tank gun 100% all sides
yes the U.S. army did evaluated the stingray as a airborne delivered tank but never as a replacement for the M1 or M60.
now the main and really only needed reason you will not see a LAV-25 used by this unit is its not a tracked vehicle.
Armored cavalry units since the early 80s have been all track units in there combat elements. Before that they were Airmobile units.
On to what I keep hearing about the army getting first dibs
1. the Active duty Army units in the U.S. are already equipped and would not need to raid the Nation Guard Depots for vehicles.
2. There a plenty of tanks for the new units to equip from in the depots.
seeing as most if not all NG units are Infantry.
now just to clarify most of what I'm saying is base of logistics and standard military Naming processors.
Now a unit like this is more likely to be a
Armored Reconnaissance Squadron which is a division level unit that would be broken-up and divided between the brigades as troop level units. and would not get over Squadron size.
