Making the k-wagen suppression a vet 1 ability would make it a 240MP garbage can with wheels.
I watched the replay and while the two KW's does give early game pressure, America can overcome by sitting in cover or flanking (both requiring good micro). If you're really worried about this strat in the future, just run your infantry to a fuel point and sit in a building or heavy cover until you can get a scout car.
Lastly, going bazooka was a mistake, you should've saved your fuel to rush out a scout car (which destroys KW's).
