I think the M3A3 Bradley is well balanced right now. It’s a very versatile vehicle—very effective against infantry, but also quite dangerous against other vehicles.
I find it especially well suited for modes like Breakthrough and Rush, where supporting the team and controlling space is key.
One piece of equipment I find particularly useful is the proximity sensor. It really helps with awareness, especially in urban combat where threats can come from anywhere.
As for improvements, one thing that could be interesting would be giving the driver access to a secondary machine gun option for more flexibility.
The best way to counter it is by attacking from the sides or rear, or in close-quarters urban fights—getting close enough to use C4 is still one of the most effective methods.
