GRAA 3.0 ACWA OFP mod by Sanctuary

I remember myself playing GRAA mod. It works nice with ECP mod too. One annoying thing about GRAA is that AI can have too big view distance - some missions are unplayable becouse of that.

Another worth playing mod similar to GRAA is FFUR 2007 mod. Besides of things which GRAA adds it is adding also healing wounded soldiers (like in Dragon Rising, soldiers which are lying on the ground and cannot fire, it also allows carrying them). FFUR 2007 adds also grass over the islands and replaces some of the vehicles.

The newest mod is ww4, it is made by Sanctuary too. I've never played it, but from what I've seen it is very popular by CWA/CWC community.
