When I’m SL or aSL and have the loud bubble chat voice I constantly yell orders to try and keep marines in synch with one another and try to form some sort of cohesion. Sometimes I even take the megaphone to get the REALLY big font and try to organize the marines on some sort of objective.
To try and bait the screech, to wait for them to come over the river, to make a firing line, to retreat and to counter push.
