I thought that Delta was a tank company and not a cavalry troop. I do not see the border on the map, the roads from East to West would have been cut by the border fences and other installations.
With the M-1s, you can fire a long ways and hit the target, destroying it while the Soviet equipment (as I understand it) was not as accurate. The M-1s primary targets should have been any ADA (APCs with visible missiles mounted not to mention the ZSUs) and then any vehicle with an antenna since only the command vehicles had radios. Also, My understanding was that the Soviet units were smaller with a tank company having only 10 tanks while the US tank company had 17. I believe that the US Cavalry troops there also had 12 M-1 tanks.
Where were the combat engineers or were they still laying fortifications? The road through the woods from Niederbieber to Margretenhaun should have had the bridge blown and an abbatis built - or more than one. There could have been mines, booby traps and Scouts keeping overwatch to call artillery down on any Soviet units attempting to remove such road obstacles. A claymore or two for mass editing of enemy ground personnel trying to remove the roadblocks would have been particularly effective, not to mention barrels of napalm giving them fits. There also could have been road craters made as well.
The helos, whether Cobras or Apaches, if they were armed with Hellfire missiles could have stayed under cover while another unit spotted for them. I thought that the observation helicotpers as well as the attack helicopters had observation and missile tracking devices placed on top of their rotors so they could track targets with very little showing. The A-10s could also have been armed with such missiles so they would not have had to make attack runs, leaving them vulnerable to ant-aircraft fire. When the enemy ADA was suppressed or destroyed, then they would have come in with their 30mm cannons.
Seek peace but keep your gun handy.
