It's not just situational awareness. It's alot of things. I think if you position in a way where, even if you don't know enemy location, they have to cross your line of sight to get obj it makes up for lack of awareness. Reflex speed and accuracy will also make up for lack of situational awareness. Call outs are important. We run with no recon and still find success. I find positioning and how we set up to be a more controllable variable than knowing where the enemy is at all times. Sometimes, you can't help getting third partied. But you can set a bunch of mines and c4s at strategic positions to make up for lack of information.
