Phantom SU-76s

[dbt1949]

I just played scenario number 1. The Pusan perimeter one.
Anyrate the NKs seem to have SU-76s but they can't be seen. Even by units with zero suppression right next to them. The USMC even destroyed a couple with return fire and there was a notice of such and little burning fires broke out in the hex but the SU-76s stayed invisible.
Also at the end of the game the USMC was not given credit for destroying them.
Maybe next time I ought to play the NK and have these "special" vehicles!
