I believe this scenario's route structure was rather poorly made. When the platoons get to their battle positions, they seem to have this sturctured position system that works good in theory, but works very poorly in the game. It is set up so that once the platoon comes under fire, it retreats back to some other waypoint and then moves to a different position close to the original BP. This is good in theory ( never stay in one spot etc. etc. ) but bad in SB because SB AI driver AI takes about a minute to figure out what it is doing ( especially if you are moving as 4 tanks ). Thus, when they finally get to the second position, the platoon has about two T80 platoons firing on it, and the platoongets massacred in no time. ( I specifically mentioned the M1A1 scenario because of the M1A1's weak frontal armor ). The only way I seem to get the scenario to work is to completely delete the second BP, get the M1s not to pop smoke (inhibits LRF) within the first two seconds of combat, and control embarking of routes myself. I believe Steelbeasts has a great tank simulation, but many of the offline scenarios need some fine tuning from the devs, or work from a third party.
