Bonus: for those who chose to fight against the PRC Marines...

You see there the PRC Marines operating with heavier support thatn those light armoured vehicles (at least in the scenarios included in their path... those Chinese BMP-1 where smashed by a combination of grenade launchers and a very daring TOW vehicle). The inclusion of any heavier armoured support in the enemy could make the game interesting (and make the aerial support available a bit more useful).
Just my five cents...
PS: My critics are constructive, I say again that you did a great job, Double Deuce.
BTW... which tanks are supporting the marines in this video?
