firing positions and concealment

When you are in a bush. You can`t be seen very easily but if you have a wider view it means that you can be seen easily. But you have a wider firing arc so like the picture shows that moving back a bit can make the difference to you being killed or being in seen. In the top picture the soldier is poking out of cover to gain a wider field of view. In the bottom picture the soldier has pulled back into the cover, reducing their field of view but also improving their concealment. A lot of players will adopt the bottom posture and "pop out" for a look and then pull back into cover again.

It's a balancing act that skilled veterans have learned over many deaths and the hard lessons this brings.

The next topic is when you are shooting over a ridge and you come up from the prone position to crouched position you can be seen really easily so you just take your shot and go back to cover. Like the picture shows. Mastering the "pop up" is a tactic most skilled players have learned. You need to learn it too, and it's sometimes useful to go onto the training server with a friend and get feedback on what your view of what you're doing looks like to a 3rd person perspective, representing what the enemy will see of you when you are doing it. That way you can match your view to how exposed you will look to the enemy when you are popping up and down behind cover.
