Here is the designers John Fernandes' take on your question:
Question: My question is this, in the Div. Cavalry Squadron,
at least in 1969 till I suspect the reorganization of the
U.S. Army division in 1986, the ACAS platoon was often
described as the smallest combined arms team in the army.
"The platoon had a scout section (4 vehicles, type varied in
this period), tank section (4), rifle section (1 squad
w/M113), and a mortar section (1 carries. The platoon leader
lead from his own scout vehicle. So the platoon had 5 scout
vehicles, 3 tanks, and two M113 vehicles."
In the rules T&OE, shouldn't the proper organization be more
accurately reflected for a ACAV troop as almost the same as
a real life platoon? By this the 9 tanks in a troop be
reflected in a wargame organization as 3 tanks, 15 scouts as
3, three rifle squads as 1, and three mortar carriers as 1?
"Answer: Not the way I see it. Your opinion is, of course
perfectly valid, but allow me to explain. As far as I know
the "Division 86" reorganization gave each Cavalry Troop 6
Bradley "Scout" vehicles with only a two-man crew for a
total of 12 men, 8 M1A1 tanks, and 2 M106 Mortar Carriers.
This resolves to 2xRecon (R) Infantry/M3 Bradley, 2 M1A1s,
and 1 M106(1).
According to the manuals I retired with, there were three
such Troops in a Squadron + a HQ and a Tank Company (I
believe). I could STILL be wrong."
Question: And as a side question, what would be the correct
organization for the wargame table to represent a ACAV
squadron in a ARMOR CAVALRY Regiment?
"Answer: According to U.S. Field Manuals dated 1988. The 11th
Armored Cav contained three troops each of 12xM3 Bradleys
carrying a total of three infantry squads., 9 M1A1 Tanks,
2xM106 Mortar Carriers + a tank Company of 14 M1A1s and a
battery of 8 M109 (I believe A2) 155mm SP Gun/Howitzers.
In Modern Micro-Armor this would be 1xTL3 Infantry(R)/M3
Bradley, 3xM1A1 Tanks, and 1 M106(1) + a Tank Company of 4
models and 1 M109A2(4).
I could STILL be wrong. Go with what YOU think is correct.
You're running the scenario! I won't be hurt or anything.

Question: Who else but wargamers care about something like
this ?
