Squid got it exactly right. He beat me to it.
Of course we use Teamspeak.
GRAW coop is a dangerous environment. since we dont have the use of our arms to point to locations etc, the system built into GRAW1 (absent in GRAW2) was great. and the swirling 3D circles of GRAW2 was even more literal and specific. but we cant apply them to human players.
Now ontrast the example that squid gave (which is what we are stuck with) to what it sounded like in my GRAW1 squad when we had this premier featuer.
"Steve, go here, keep your eyes focused west"
"Bob, advance beyond Steve, to here, eyes north in transit"
"Bill. Covere here".
Qiuck, precise, non ambiguous. The technique of bounding overwatch for squad movement becomes a reality adn the expereince flows as it should. squad interaction gets oh so way tight.
It was the single best expereince of GRAW1 by far. its gone in GRAW2.
