There's already a lot of questions regarding the platoon data, so better get this one started too. As always, any questions just ask!
Why is this important? The game ships with a NoEncryption option (-X launch command for me.exe), so it is perfectly possible to modify the values and then enjoy the game play (vs. AI only).

Note: Unit Viewer reads the unencrypted OOB files from /OOBs folder, and not the encrypted OBX files. It is your best friend when modifying platoon data.
Note: Use JSGME! The game is very delicate to erroneous data. You have been warned.
So here goes. First, a set of Egyptian units as they appear in the Unit Viewer, with SA-6 SAM selected:

Here's the snippet of Platoon23.oob file as visible in the Unit Viewer listbox, with the SA-6 SAM selected in bold font:
