If you want to go into this without your head exploding..... this is the MTOEs from the US army in the 90s when they were going through the transition to Force 21. I was able to decipher it because I work with the unit manning reports (UMR) and MTOEs. In the first collum on the link shows how many of each type of company are in that battalion. The second collum gives major end items each company has. If you click on the links, into goes into ALL the details. You can find out how many E-3s are in every platoon if you really want, or how many wreckers or fuelers are in each battalion.
Some advice, go to the Divisions that don't have XXI and you'll get the real cold war style units. Also, when you click on the links, there are two collums, the one on the left that says BTOE and the one on the right says OTOE. You want the OTOE. The BTOE has the right type of vehicles not MTVs but old duece trucks, and 4.2" mortars instead of 120mm. But the problem is that they deleted most of hte support vehicles. . Some of the hidden codes:
tank, 105mm = M1IP
carrier cp = M577
TRK wrecker and TRK Tank Fuel are the HEMMTs
carrier 120mm mortar = M106
carrier armored = M113
Strangely, I saw no mention of the battalion's scout platoon. They typically had 8 M113s/M901s....
