In Battlefield 4 there are wide variety of rocket launchers (guided, unguided, etc.).
What launchers are most effective, in terms of available ammo and dealt damage?
What is best weapon to have against tanks, without friendly support with additional ammo?
Answer
To take down a tank all by yourself, the best way is C4. It takes 3 C4 to be sure to kill a LAV, tank or boat. Jeeps and Armored transport (Humvees, Vans, etc) takes 2 for a sure kill.
Note that 2 piece of C4 might kill a tank if you put them on the right spot (mostly on it’s rear from what I found). If you put two pieces on the sides, it will disable the vehicle and leave it burning giving time to the driver to jump out. If you put the 2 pieces of C4 on the front, it will disable but not put the vehicle on fire.
1 piece of C4 does a mobility hit for sure which can allow you to put more C4 instead of the tank running off.
Mines are also a good way to take care of tanks, but you must place them near it and hope it runs over it (or shoot them with the Rex/magnum/slugs from shotguns) or place them in popular spots for vehicles to get that random kill 5 minutes later.
For the launchers, this is what I found:
Also, I found this forum post:

For the damage stats versus vehicles per launchers, I could not find the stats. But I’ve heard that RPGs do the same damage as a tank shell. The angle is (like in BF3) primordial in BF4. If your rocket hits at 50 degrees, it will do around 20 to 25 damage while hitting a tank square on will do a disable in most cases. Tanks are also more resilient on the front to damage. Sides have less armor and even less armor to the rear.
Overall, killing a tank alone is easier with C4 since a good tank driver will rarely get killed by one engineer. However, to maximise your rockets potential, doing a 90 degree hit on the rear of the tank is the most effective way to kill it and the RPG is the one doing the most damage according to what I read.
Also, repair tools work wonders if you can sneak up on the tank, but that usually ends up in a suicide when the tank blows up (in BF3 you could survive with less than 10 HP, but in BF4 even if I stay at maximum Repair tool range, I still die).
