Thanks for the help guys. So I tried the first mission of the lightning campaign tonight with a couple weird results... I told 2 M1A1s to perch themselves on the berm to their immediate right as a sort of "take a peek" armored recon as my first move. This they did fine but they were parked on the reverse side of the slope with their barrels fully depressed and still pointed at maybe 20 degrees up from the horizon line. Yet they were shooting at and taking out targets that were below the horizon, looked bizarre (never saw anything like that in CM 1 games). So I order the remaining 2 M1A1s next turn to drive past the 2 on the berm and into the flat area beyond. I assumed that since the first 2 could climb the berm these next 2 would be able to climb it as well and then drive a further 40 yards or so. Hehe, they decided to go for a drive *all* the way down to where a road bisected the berm where they exposed their flanks U-turning back to the destination I gave them, a T-55 immobilizing one of them.
Ah well, on the positive side I can say the vehicle models look great.
