CoH: Modern Combat

I just played Yongxing Island. Two Marine Scout squads landed and went to the communication station.Marines called the fighter and the fighter destroyed the communication station.Then Marines destroyed the PGZ-95 Air Defense System by the AT4.Then the game told me that another goal was to kill all PLA Snipers.Then I found that I could choose a squad by the mouse but I couldn't move any squads.I still had 1 minute left but the timer stopped.I didn't know how to continue.I thought it might be a bug.Please fix.
Another thing is that when I use PLA Marine Camo,the PLA Militia, Regulars and all the other soldiers (except the engineers and the snipers,the engineers are in blue camo) wear a pink cloth. Only the Regulars' helmets are still green.I don't know why.Then I produced a T59D tank.But the T59D are still in green camo,not the marine blue camo.
And,can the PLA regulars wear Type 07 Ocean Digital Camoflage and Ocean Digital Camoflage Helmets?I think it's more suitable.

I played it again and I found that if the USMC destroyed the two PGZ-95s, the game would have a serious error and stopped. I hope the bug will be fixed and the mod will be better.
