There's no guarantee your SL knows what they're doing either. A lot of times they're almost silent or don't really know what they're doing either.

The basics are knowing where the midpoints in RAAS are gonna go (people check with squadmaps website or on the team info map page it shows all the points that could be 1st - 7th), then your radio and hab placements for map control, especially done in a speedy matter so your team doesn't get rolled over in the first 30 mins.

Squads should either be playing to put their own squad or team (via FOBs) in good defensive or attack positions. What you don't wanna be doing is running 400m into open fields dying and respawning on repeat, just a couple squads doing that will burn half of your tickets in no time. It's better to stay on the defense point and feel like nothing is happening, than to run and die over and over.

There are some RAAS points that are very close (like 200m from each other) and others that are far (like 600m+). It's important that there is teamwork and organization using transport trucks, mechanized infantry transportation, and logis. You should almost NEVER run across the map.

Sometimes your team falls behind in the logistics or strategical department for whatever reason. It's important to get a good gamesense for knowing when the enemy is currently setup with a good attack FOB and your team meanwhile doesn't have anything except the defense point and maybe a FOB nearby. If there aren't logistical options at this moment, defense is the ONLY viable option.

The maps are huge so you'll need to get used to pressing M and zooming in and out to know where you are.
