When in Vehicles, Preserve Cover on Your Side of the Map
One of the more frustrating trends that I've seen with the increased destructability in Battlefield 6 is when someone takes their tank or other vehicle and just mows through walls and buildings to sit on the point before rolling on toward the next target.
By doing so, you're robbing your team of valuable cover when the enemy team is pushing further toward your side of the map. If your first thought is to think that their vehicles will destroy your walls, that is absolutely plausible and likely. But they have to get there first, and your engineers and other roles can help repel from behind cover a bit more easily. A building or other cover will destroy more easily when driven through vs. shot at.
By depleting the cover, you're opening your team to long range fire from infantry when in those areas. It is harder to revive without cover, too. Will the cover eventually get destroyed? Possibly. But if you take down fortifications for them, it's gonna make their job easier to clean up the back line.
