BF6 Tanks weaponry too weak

Too many times have I found stragglers or lone wolf infantry maybe 3 at most and used all different tank models I've fired on enemy at a decent range with the secondary grenade launcher, machine guns, rockets, etc... I may get one kill even if I run up point blank 20 meters or so firing down on these campers and it's as if my bullets or rockets do no or hardly any damage to them. I've quit literally blasted people straight up with a rocket or secondary machine gun and then they kill me with a rocket launcher. Why are the tank weapons so weak battlefield appeal is realism and last I checked if I shot you with a missile while your on a turret machine gun it should obliterate you not you being able to hope off and nuke me with a RPG. If a grenade can kill me from 10 meters I'm fairly center a tank missile would disintegrate you. EA please fix the damage from tanks they literally become useless with infantry not taking damage and helicopters blowing you up instantly.
